We caught up with a few of the celebrities to find out who they thought would win big this weekend at the Oscars.

DJ Pauly D. told us that he was rooting for "his man" Brad Pitt in Moneyball in his favorite movie of the year. How did he prep for the evening? He said his hair alone takes 35 minutes and the rest takes only five.

While Derek Hough told us that he will be on this season of Dancing With the Stars and he will be meeting his partner for the first time this weekend. Although he has been trying to bribe his producers to give him a few hints about the new cast, he swears he is on the dark about his partner up to this point. Derek doesn’t have a favorite pick for the Oscars, he thinks it will be a tough year.  

American Idol’s Pia Toscano picked out her own gorgeous dress that she found in a boutique on Melrose and looked absolutely stunning. After being a fan favorite on American Idol, she tells us that she does keep in touch with a few of her former Idol contestants and thinks that this will be an exciting year with the bar being raised higher each season. While she has no specific favorite contestant, she tells us that she doesn’t even know how they are going to narrow if down from the Top 24 to the Top 12. Who does Pia think will sweep the Oscars? She is rooting for The Help.  

Emmanuelle Chriqui and Richard Grieco also came out to support Adrian Grenier. 

Bai Ling hit the red carpet in a shorty sequin dress and edgy necklace.

When we asked man of the hour, Adrian Grenier if there would be an Entourage movie, he told Starpulse exclusively, “You better believe it, you better believe it.” But right now, he is very excited about his film Teenage Paparazzo, depicting the dangers of celebrity and paparazzi to youth today.

Sex and the City actor and former Dancing With the Stars alum, Gilles Marini says his time on the show was a long, hard process because he had never danced before but thought he did pretty well. Gilles’ picks for The Oscars include The Artist and George Clooney.
