Bad Manners: Aniston Snickers at Brad Loss, And Did Angelina Have to Force Brad to Congratulate Winslet?

Brad Pitt, Angelina Jolie and Jennifer Aniston were all smiles when they knew the cameras were on them at the Academy Awards on Sunday night, but in two instances, two of the three-headed monster were caught letting their true feelings show.

First, as Michael Douglas announced Sean Penn as the winner for Best Actor, Aniston, who was seated directly behind the "Milk" star, showed obvious satisfaction that her ex-husband, who was also nominated, wouldn’t be taking home the honor with an undeniable snicker.

But it also looks like Pitt was caught being less than chivalrous.

When the auditorium erupted into a standing ovation for Best Actress winner Kate Winslet, Jolie, who was also nominated, was quick to stand up. But Pitt stayed seated.

It wasn’t until Jolie bent down and seemingly whispered to her man to make a move that he hesitantly rose to feet.

Hmmm… sour grapes, or just sheer laziness?

As reported by Pop Tarts earlier this week, Aniston is apparently in such amore with beau John Mayer that she’s totally ready to come face-to-face with her former husband and his leading lady - and based on her reaction to Pitt’s loss, she certainly is having the last laugh.

Lindsay Lohan a Mess; Sheryl Crow Drops F-Bomb on John McCain for No Real Reason

So much for rehab! It seems Lindsay Lohan really is back to her wild and wasted ways. The scarily skinny actress joined girlfriend Samantha Ronson at the Global Green Pre-Oscars party on Thursday evening, but according to inside sources was anything but on her best behavior.

We're told Lohan was knocking into people on the dance floor and at one point even fell into a wobbly heap in the early hours, prompting security to rush over and check if she was okay. Linds is also back to baring all and this week engaged in a topless, provocative photo session with famed photog Hedi Slimane .

Sheryl Crow also performed at the eco-friendly affair, but in between one of her songs felt the need to bash former presidential candidate John McCain."Let's hear it for Global Green! We have new President who will make a difference in the environment," Crowe told the audience. "F**k John McCain."

Alrighty then.

Also in attendance at the soiree was Hayden Panettiere, Gavin Rossdale & Gwen Stefani, Tyrese Gibson, Jamie King, Kate Bosworth, Neil Patrick-Harris, Rosario Dawson and Heather Graham .

Pop Tarts also caught Crow’s performance the night before at the Children Mending Hearts Foundation dinner at the House of Blues. Ben Affleck stirred a swirl of emotion with an inspiring speech about getting involved to help those being affected by rape, murder, and torture, and championing the work of International Medical Corp. Affleck (along with wife Jennifer Garner, Andie MacDowell, Benji Madden, Nicole Richie, Bridget Moynahan plus many more) even took time out to sign the Wonderwall.com page with a heartfelt message.

MyHouse Goes DogHouse: Pooches Party While Celebs Are Left Outside

Divas, divos and dogs aligned at Hollywood hotspot MyHouse on Saturday night to support the "Tag the World" animal charity and the American Humane Association. But while Holly Montag, Stephanie Pratt, Tila Tequila, Karina Smirnoff, Shia LaBeouf and even the "Marley & Me" dog were let inside, other stars were given the cold shoulder by the oh-so-powerful door peeps.

We’re told Terrell Owens was made to wait (apparently he was cool about it, but his entourage was frothing at the mouth) while Joey Fatone had to stand outside and could only bring in a few friends. Comedian Jamie Kennedy was also kept out for quite some time and several of the charity big-wigs were denied entry to their own gig. So even thought the club is called "MyHouse," we’re told the promoters weren’t too happy about having canines chill out in their abode.

Did Jennifer Aniston and Heidi Klum Have the Worst Hair At the Academy Awards?

That's what Beverly Hills hairstylist Tina Dizon of the famed Juan Florentino Salon says.

"Aniston’s braid, it was a little outdated and casual. She's such a beautiful person that I think it's time she should break away from the safety of her hair," Dizon told Tarts. "And Heidi Klum is usually always a knock out, but her hairstyle was a little too slick, which made her hair color too obvious - too light in front and the dark and light of her colors are too noticeable."

According to our expert, Melissa George, Lisa Rinna and poor ol' Mickey Rourke also kinda fell flat in the hairy area. So who were the "locky" winners?

"Marisa Tomei - that soft, wavy side-swept hair was so elegant and romantic. Penelope Cruz was very Audrey Hepburn and oozed simple, but classy elegance," she added. "Amanda Seyfried brought back old Hollywood glamour with a touch of new Hollywood youth. Frieda Pinto's hair was simply pulled back to not take away from the design of her blue Galliano dress. And Natalie Portman looked angelic and composed with the soft waves of hair pulled back, simple and beautiful."
