Jessica Simpson Shares First Photos of 'Daddy's Girl' Maxwell Drew
First-time parents Jessica Simpson and Eric Johnson unveiled the first photos of daughter Maxwell Drew in this week's People.
The new mom gave birth by cesarean section May 1, with fiancé Johnson at her side. Since then, "life has completely changed," Simpson says in the magazine's cover story.
"She's my career at the moment. I know I was always meant to be a mom, and I think I'm doing a really good job. I'm the most aware I've ever been."
Jessica Simpson Poses Nude and Pregnant
The 31-year-old singer adds that caring for "Maxi" or "Max" has helped her keep a handle on her responsibilities.
"It's the first time I've ever kept to a schedule in my life! I'm always making sure she's had as many poops as she's supposed to have and that she's being fed at the exact time she's supposed to be fed."
As for Johnson, 32, the experience has been "emotional."
"When you have your own kid, it's crazy," the former NFL player says. "It's such an intense love, and so natural."
Hollywood Star Athletes
"He has found his calling," Simpson says. "Maxwell's definitely going to be a daddy's girl!"
While the couple have yet to solidify plans for a wedding, it won't be too far in the future — according to Mom.
"I'd love to do it before the end of this year, but you just never know. I haven't set a date yet," she says. "It's going to be one of the most amazing weddings of all time."
As for baby No. 2?
"Having babies back-to-back has to be so hard, but I won't wait too long!"

text: There are no ill effects, except as mentioned for possible recovery scenarios to a particular point in time. If you are using DATE datatypes in your tables, you're OK. Just be aware that when you update these DATE datatypes from SYSDATE, you will be using the value of the system clock (which you have adjusted - whether it be a correct or incorrect time). I think Dick is saying that "tiemstamp with local timezone" is always converted to GMT. One other thing to remember when you are fooling with the system clock - cron jobs and database jobs may suddenly think they need to run. In 1999 I had the brilliant idea of setting my PC clock to some date in 2000 to test a potential Y2K problem that I read about. I was using Groupwise at the time for email and appointments. Suddenly I got hundreds of alerts/alarms for all the meetings that I had scheduled between the actual date and the new date I had just set on my PC!

On May 6th, 2009 Maine became the first state in the country to legislatively grant same-sex couples the right to marry. Seven months later, on November 3rd, a vote was taken to approve an amendment to take away this right. Filmed from within both campaigns, QUESTION ONE chronicles the fierce and emotional battle

Think We Are Headed For A BCS Controversy? Think Again.
There's one topic that has taken the college football world by storm the past few weeks: If three or more of the remaining undefeated teams stay unblemished through the regular season, who gets left out of the BCS National Championship game?
Whoa, whoa — hold your horses, fans.
There are six undefeated teams left in college football right now — Alabama, Oregon, Kansas State, Notre Dame, Ohio State, and Louisville — and five of them are eligible for postseason play, with four having a shot at the national championship (sorry, Louisville — but on the bright side, you are the only school in the country with a top 10 team in football, men's and women's basketball right now, so go celebrate).
However, is having six undefeated teams after ten weeks even that unusual? Not really, as it has happened in four of the past ten seasons:
Undefeated Teams of the Past Decade
Wondering who the specific teams were those years? Here they are:
So what does it all mean? That teams fall off by the end of the year, and very rarely do BCS conference teams make it through the regular season undefeated and NOT get a chance to play in the national title game. While there have been 11 teams in the past 10 years to go undefeated and get left out of the title game, only two of those came from major conferences — 2009 Cincinnati and 2004 Auburn. The rest (Boise State four times, TCU twice, Utah twice, and Hawaii once) were good teams in their own right, but their strength of schedule left much to be desired.
Maybe you think that this year is different. After all, it isn't very often that you have teams who break rules and get declared ineligible for postseason play. In that respect you'd be right, but it still appears unlikely that we will have too much championship controversy:
There is currently a 7.1% chance that Alabama, Notre Dame, Oregon and Kansas State are all undefeated on December 2… ow.ly/f4s8L
— Paul Bessire (@predictmachine) November 6, 2012
There is still a lot of drama left to come in the next four weeks (Alabama vs. Texas A&M, Notre Dame vs. USC, and Oregon vs. Stanford come to mind) but don't be surprised if things shake out in a way that leaves two clear title contenders ready for the big fight. College football is a gauntlet that is hard to survive unscathed, even if the end appears near three-quarters of the way through the season. After all, history tells us not to worry — somebody will drop in the coming days.
