Dakota Fanning celebrated her sweet 16th birthday with a sophisticated dinner party at Villa Blanca in Beverly Hills. The actress, whose big day is Feb. 23, was joined by 40 guests, including girlfriends from her cheerleading squad and her longtime private teacher. “Dakota looked adorable in a white blouse with a sequined, silver skirt and high heels,” an eyewitness tells us. After guests sang “Happy Birthday,” Fanning blew out the candles and thanked everyone for joining her for the Mediterranean-inspired dinner.

Says the eyewitness: “She seemed very excited and touched about celebrating her special day with her family and friends.”

In the 2009 pilot season, Smart (“Varsity Blues”) starred in “See Kate Run” for ABC. In 2008, she did “The Meant to Be’s” for CBS. Her 2006 pilot, “Smith,” was ordered to series by CBS, but lasted only three episodes.

Keira Knightley’s stint in West End production The Misanthrope may have fetched mixed response from the critics but the Bend It Like Beckham star is looking forward to spend more time on stage.

The Oscar nominated actress is ignoring criticism of her performance in The Misanthrope and wants to appear in more productions in London’s West End.

“It’s so different to films as you really get into the character. In films, once you have finished shooting a scene it’s done but with theatre you’re always continuing. You get to know the character in a way that you don’t as much in films,” Knightley said.

Cox, 45, underwent in-vitro fertilization for her first pregnancy at age 39.

“I don’t know. I mean, it takes a lot for us to do it, so maybe adoption,” Arquette, 38, said on “The Bonnie Hunt Show.” “Listen, I like practicing as much as possible! But it’s hard … I’m exhausted!”

Last year, the National Enquirer reported that the couple was planning to adopt a child after Cox “reached a point where she feels it’s hopeless to keep trying to get pregnant.”
