Story highlights First lady welcomes veterans and stars to "Star Trek Beyond" screening at White House 
 
 Missy Elliott pops up for Michelle Obama's "Carpool Karaoke" 
 
 (CNN) It was a starry night for the first lady. 
 
 Michelle Obama not only had her "Carpool Karaoke" with James Corden air on late night Wednesday, but she also had a few stars over to her home Tuesday. 
 
 Obama hosted a special screening of "Star Trek Beyond" for a group of veterans and military personnel at the White House along with actors Chris Pine, Karl Urban and Simon Pegg. The event was attended by more than 100 vets, military members and their families as part of the first lady's Joining Forces initiative. 
 
 But it was her appearance on "The Late Late Show With James Corden" that stirred the most buzz. 
 
 Obama rocked out to Beyonce's "Single Ladies," discussed her Secret Service code name and was joined by rapper Missy Elliott.

 For several months America has been obsessed with what will happen once either Hillary Clinton or Donald Trump is elected president. But there is one important question no one has been posing: what the hell are we going to do without Michelle Obama? Not since Jacqueline Kennedy has there been a first lady as charming, glamorous, or inspirational. 
 
 All of those qualities were on display during her chance to do Carpool Karaoke with James Corden. From the moment she strapped on her seatbelt and started singing Stevie Wonder’s Signed, Sealed, Delivered she had the audience in the palm of her hand. It turns out that Michelle doesn’t have a bad singing voice (though you couldn’t get the full extent of it with Stevie and James carrying the track). 
 
 It was a bit shocking to learn that Ms Obama has only been able to ride in the passenger seat of a car and rock out to music once in the last seven years – when teaching her daughter, Malia, how to drive. I would watch a whole documentary about learning to drive at the White House. 
 
 Speaking of which, the strangest part of this Carpool Karaoke is that Corden is only allowed to drive around the White House driveway repeatedly, which is presumably how Malia learned to drive too. It removes the improvisational nature of the exercise, since there’s no dealing with traffic or actual driving. 
 
 Regardless, it was great to see Michelle Obama doing the Single Ladies dance while singing along to Beyoncé, entering the Beyhive “and making honey to put in our Lemonade”. The two may be friends, but it was Beyoncé’s former band mate Kelly Rowland who Obama called up to sing This Is For My Girls, the anthem for her Let Girls Learn initiative that is helping draw attention to the 62 million girls around the world who aren’t in school. “So much could be corrected in the world if girls were educated and had power over their lives,” she says. Yes, whenever Obama does something fun like this it’s because she has an important message to deliver. 
 
 Missy Elliot does a guest rap on This Is For My Girls and she popped up in the back seat to deliver her verse, then joined Corden and Obama on Get Ur Freak On, a song whose lyrics didn’t seem to phase Michelle one bit. It turns out she can really spit some flow too. But is that surprising? Over the past eight years we have learned that Michelle Obama can do absolutely anything – from teaching kids to exercise to delivering epic levels of side eye. Neither Bill Clinton nor Melania Trump would be nearly as fun to watch. ||||| The fated day has finally arrived. On Wednesday night, Coolest First Lady Michelle Obama went for a quick spin with James Corden on The Late Late Show and performed an instant-classic round of Carpool Karaoke—with an unexpected guest at the end, Missy Elliott. It’s official: we, the people, have the most viral First Lady ever. 
 
 Obama and Corden started by jamming to one of her favorite artists, Stevie Wonder’s “Signed, Sealed, Delivered I’m Yours.” Obama admitted that she hasn’t gotten to rock out in a car in ages, which makes this momentous occasion (almost) as special for her as it is for all of us. Another fun fact? According to Obama, her Secret Service code name is “Renaissance,” and Barack’s is “Renegade.” 
 
 It wasn’t long before the focus shifted to girl-power jams: first, Beyoncé’s “Single Ladies”—which, we should all note, Obama knows by heart, complete with hand-waving choreography. Next up? “This Is for My Girls,” a song Obama herself pulled together for her Let Girls Learn initiative with female icons like Missy Elliott—who, what do you know, just happened to make an appearance for her rap break. As Michelle presciently noted, it seems a new powerhouse squad is forming—a “girl-power squad.” 
 
 And to finish? Let’s just say that Michelle could hold her own on “Get Ur Freak On” at any karaoke bar in the nation.
– It's been almost eight years since Michelle Obama was able to sit in a passenger seat and sing along to the radio, so it's a good thing James Corden stopped by the White House recently. In the latest edition of Carpool Karaoke, Corden drives Obama repeatedly around the White House driveway as they belt out tunes from Beyonce, Stevie Wonder, and Missy Elliot, who makes a surprise appearance. A few takes: "It's official: we, the people, have the most viral First Lady ever," writes Laura Bradley at Vanity Fair, noting Obama knows Beyonce's "Single Ladies" "by heart, complete with hand-waving choreography." Obama "doesn’t have a bad singing voice" and "can really spit some flow too," writes Brian Moylan at the Guardian. He compares her to Jackie Kennedy and wonders what we'll all do without her come January. Meanwhile, Elliot tells CNN that she thought she was dreaming throughout. "I know for a fact that it was all over my face like, 'Wait, is she rapping this?'" she says of the moment Obama started spitting her rhymes. "But that goes to show you just how cool she is. People hold her in such a high regard—as you should—but she's so down to earth." The video—in which Obama reveals her and her hubby's Secret Service code names—even drew a shout out from the agency. "Thank you @JKCorden and the @latelateshow for bringing @FLOTUS home safe and sound after #CarpoolKaraoke. We were watching," it tweeted. (Carpool Karaoke is becoming its own show.)
