Aniston, Crow in Midst of Birthday Blowouts

By: Betsy Waldman / February 7, 2009

In a true showing of celeb birthday bonanzas, pals Sheryl Crow and Jennifer Aniston are celebrating their mutual big days with consecutive nights of parties this weekend.

The two, who were both born on February 11th, are splitting the weekend to mark the occasion, according to a Us magazine.

“She’s having a party and I’m having a party,” Crow told the mag. “Mine is on Friday and hers is on Saturday.”

While Crow is turning 47, Aniston is officially turning the big 4-0 next week. Aniston told Ellen DeGeneres this week that she was saddened when she found creeping grey coming on.

“I found a really long gray hair, and it kind of flipped me out,” she said. “It’s not my first, but it’s the fact that it was so long. I was like, ‘Oh, that’s been there. How many others are there, and what does that mean? It actually brought me to tears, slightly.”

Aniston also discussed her party on the Ellen show saying that Courteney Cox would definitely be attending as well as Cox’s husband David Arquette. But she would not confirm whether on-off boyfriend John Mayer would attend.

As for Crow’s love life, a source tells Celebuzz the singer showed to a book party for author Andrea Buchanan’s new tome “Note to Self: 30 Women on Hardship, Humiliation, Heartbreak, and Overcoming It All.”

Yikes. We’re told Crowe opened up about her split from cyclist Lance Armstrong. No worries on running into him at her or Aniston’s birthday festivities this evening.

According to the Livestrong athlete’s Twitter, he’s spending the weekend riding bikes with pals through Southern California.
