Pete Wentz took his son Bronx on a walk around NYC yesterday and that little muffin was crying his face off the whole time. Poor guy was probably freezing, not to mention freaked out that there were guys taking his picture so that an asshole like me could later buy those photos and then post commentary about them on the Internet. It’s either one of those things or his father’s hair smells as bad as I assume it does. I don’t hate Pete, but I hope the dude turned around and gave his kid a cookie or something. Regardless, it’s clearly hard work being one of the cutest babies in the game.

Purdue University students have a reason to be pissed at Lady Gaga. The singer cancelled her show at the school on Thursday at the last minute, claiming to be sick. Then today, less than 24 hours later, Gaga took the stage at The Oprah Winfrey Show looking not even slightly ill. In fact, she downed a plate of chicken and waffles before her performance. The Purdue concert has been rescheduled, but I’m thinking that there was no illness and homegirl just wanted to rest up for her big day with Lady O.

As for the Oprah performance, which I will totally be watching, Gaga performed a medley of her hits and according to the AP, “at one point, swung a gold, spiked ball on a chain into the windshield of a taxi on the stage.” Sounds awesome, but definitely not like the behavior of a woman who was too sick to fulfill her contractual obligations just shortly before.

Also, I don’t know if musicians realize what a big deal it is when they cancel a show. I will never forget when Christina Aguilera and Destiny’s Child bailed on a show when I was fifteen while I was already at the venue. Totally devastating, especially consider the fact that I was living in the middle of nowhere and even just the idea of Christina and Beyonce performing just yards in front of me was the most exciting thing to happen all year. I wonder if Lady Gaga would have cancelled if she thought about all the drunken college kids who had been waiting what seemed like their whole lives to get their grind on while she performed “Just Dance” in the same room as them.

My former employer, Gawker, posted People Magazine‘s Heidi Montag plastic surgery before and after today. She looks like an alien.

Heidi claims to be addicted to plastic surgery and had 10 procedures done in one day recently. A couple years back, Heidi was open about the work she had done to her nose and breasts and said they were quirks that had bugged her her whole life. She is 23 years old and has an entirely different face from when we first met her on Laguna Beach as Lauren Conrad’s friend from college. Addicted to plastic surgery? I’ll second that.

Heidi attributes her constant need to strive for physical perfection to– what else?– Hollywood and the pressure to be beautiful. Sadly, I wouldn’t put it past her to not realize how completely cliched and stupid that sounds, especially since she’s completely mangled her face. As Gawker pointed out, if her goal was to achieve perfection for the cameras, then leaving her face recognizable would be important. (More photos– some NSFW– available here.)

Mischa Barton was snapped heading back to her hotel room in New York last night after a shopping spree at one of the city’s finest and most exclusive retailers, Burlington Coat Factory. A vision in faux leopard, Mischa breezed past the photogs holding one of the store’s signature satchels and attempted to flash the cameras a modest look to assure the folks back home that big city life hasn’t changed her. There’s no fooling these eyes, though. That is one top shelf lady who only deserves the finest in moderately priced outerwear.

Tila Tequila is freakin’ me out, man. Whenever I check her Twitter these days, I get so nervous. If she’s not ranting about someone crossing her, she’s announcing unrealistic plans (Ambassador to Vietnam? Yeah, OK!) or talking about herself like she’s some wild, sexual being. She doesn’t appear to sleep, have any friends offline except for Meghan McCain (and who knows when the last time they actually saw each other was) or realize that her behavior is odd. She’s always like this, but the last couple of weeks (since her fiancee Casey Johnson died) have been truly off-the-charts insane.

Then today we find out that Tila’s publicist quit and she’ll be representing herself until she hires someone else. Considering her last rep seemed to peace out on her because she couldn’t deal with the insanity, I don’t know if “one of the biggest PR firms out there”, as mentioned in her Tweet, would be interested in trying to deal with her. That’d be like CAA signing Lindsay Lohan in the middle that DUI spree she had a couple years back. The chick’s a liability.

“Um, right now I’m trying to just finish my record and getting through the last season of Gossip Girl for right now. So not so much thinking about that.”
