ATHERTON, Calif. -- Pop singer Lady Gaga was among the guests at a Silicon Valley fundraiser for President Barack Obama. 
 
 The intimate gathering was held under a tent in the yard of Facebook chief operating officer Sheryl Sandberg on Sunday night. Gaga wore a black, sleeveless gown and high heels, and with her hair piled up she towered over the Silicon Valley elites who were paying up to $35,800 per couple to attend. 
 
 Gaga attended as a paying guest. She said last week that she wanted to meet with Obama to discuss her concerns about bullying, but it wasn't clear whether the two would be having that discussion. 
 
 UPDATE: The White House traveling press corps pool offered additional information on Gaga's appearance at the event. The pop star sat in a middle table, standing when the President entered. Obama spoke for eight minutes, and did not acknowledge Gaga, but, according to the report, "it seems likely the two crossed paths during greetings inside the house before the dinner." 
 
 Given the outfit she was wearing, avoiding Gaga was probably impossible. 
 
 "She was wearing a floor-length sleeveless lacey black dress," the pool report relays, "her blonde hair was gathered in a bouffant up-do adorned with a black hair piece with a black veil down the back, which she swept to the side and in front of her left shoulder. (The hair added about 6 inches to her stature)." ||||| But she soon will – after ordering diamond implants in her gnashers. 
 
 Simply Red's Mick used to have a ruby buried in one of his pearly whites, which deflected attention from his unpleasant moon face. 
 
 But to celebrate the start of the 21st Century he replaced it with a diamond. 
 
 And GaGa, who is no stranger to peacock-style attention seeking, has ordered a selection of marquise-style gems to brighten up her chops. 
 
 She'll have them fitted in time for the Thierry Mugler fashion show in Paris at the end of the month. 
 
 A source said: "She's still deciding how many to get done. Her dental bill will be as expensive as her jewellery bill." 
 
 Her Dutch designer Otazu also let her dental plans slip. 
 
 He said: "She'll be fitted with marquise diamonds." 
 
 GaGa will have to be careful she doesn't chip her china tea cups with razor-sharp diamond gnashers. 
 
 But they will look lovely with a hamster wheel on her head. 
 
 She definitely isn't scared of the dentist. She had cosmetic fangs fixed to her eye teeth not that long ago. 
 
 Lil Wayne has diamond-encrusted teeth and he can't eat anything solid. 
 
 Sounds a bit like a secret GaGa diet strategy. ||||| Woman loves Lady Gaga. Lady Gaga doubts woman's good faith. Love conquers Lady Gaga's doubts. 
 
 Sounds like theme of a Lady Gaga hit song, but instead, this is the plot line of a dispute involving the domain name, LadyGaga.org. 
 
 In August, the artist formerly known as Stefani Germanotta submitted a complaint to the National Arbitration Forum that alleged that the website ladygaga.org was registered in bad faith and in violation of her trademark.

 The owner of the site then responded that it was merely a non-commercial, unofficial fan site for Gaga that "does not have any sponsored links or links to third-party websites which market and sell merchandise bearing Complainant’s trademark.” 
 
 The owner added that her fan site supported Gaga's fame and was giving the singer free publicity. In other words, the site owner (identified as "Miranda") loves Lady Gaga so much that she's willing to erect a digital shrine to her, and lawyers shouldn't interfere.

 If that's not fandom, what is? 
 
 The owner of LadyGaga.org got her reward on Wednesday when three panelists at the National Arbitration Forum ruled that Lady Gaga had failed to show that respondent lacked legitimate interest in the disputed domain name. So the site can continue.

 Las Vegas’ hottest resorts don’t meet the standards of Lady Gaga, who insisted on a room with a private pool. 
 
 Sources say the superstar was on the edge of a meltdown when she checked into the luxurious Cosmopolitan hotel, which boasts three different types of pools — a “relaxing” one, a day club and a nightclub. But with no private pool, she immediately checked out and headed for The Palms Casino Resort. 
 
 “She checked into the Cosmo, was unhappy with the room, checked out and then went to The Palms, but still wasn’t happy and was frantically searching for a new room,” a source told us.

 A Cosmopolitan spokesperson confirmed, “Lady Gaga did check out of the property, but she did not hate her room and had nothing but praise for the arrival staff, butlers, etc. She was looking for a private pool, which the resort doesn’t offer.” 
 
 Gaga’s rep, Amanda Silverman, said: “It was not a whole drama. She moved to The Palms to do a recording. She had some meetings. She switched because she had stayed at The Palms before. It wasn’t like she hated her room, she doesn’t care about that stuff.” 
 
 The Palms, where the lady monster is still staying for the weekend, comes equipped with a private recording studio. 
 
 Gaga is in Las Vegas performing at the iHeartRadio music festival along with Jay-Z, Alicia Keys, Coldplay, The Black Eyed Peas, Steven Tyler, Jennifer Lopez, Kenny Chesney, Sting, Bruno Mars and Usher. 
 
 Sources say arrangements around the concert, to promote the free online digital radio station, seemed chaotic. “It’s strangely radio silent,” a source said Friday. “Nobody, like the casino hosts, knows what’s going on with the concert. The set times haven’t been announced … Most of the artists … aren’t being paid and are more concerned with their deals at the nightclubs, which are paying them to perform later in the evening.”
– Lady Gaga getting diamond tooth implants? It might be hard to believe—if the singer wasn’t already known for her avant-garde fashion decisions. “She's still deciding how many to get done. Her dental bill will be as expensive as her jewelry bill,” a source tells the Sun; her designer confirms the plan. Gaga has reportedly already ordered the marquise diamonds, and will have them in for the Thierry Mugler fashion show this month in Paris. In other Gaga news: She nearly had a meltdown in Las Vegas when she realized her room at the Cosmopolitan hotel didn’t come with its own private pool, a source tells the New York Post. She did move to The Palms, but a Cosmopolitan spokesperson and Gaga’s own rep deny there was any drama involved. While in Vegas to perform at the iHeartRadio music festival, Gaga dedicated her song “Hair” to Jamey Rodemeyer, the teen who killed himself after being bullied over his sexuality, E! reports. “I lost a little monster this week and I'd like to dedicate this song to him,” she said. “Tonight, Jamey I know you're up there and looking at us and you're not a victim. Bullying is for losers.” A big Gaga fan got good news last week when National Arbitration Forum panelists ruled that she can continue running LadyGaga.org, according to the Hollywood Reporter. Gaga had submitted a complaint to the forum alleging that the site violated her trademark, but the site owner insisted that because her site is a non-commercial, unofficial fan site basically giving Gaga free publicity, it should be allowed to continue.
