Heidi Klum and Sandra Bullock: Girls Just Want to Have Fun

Single ladies Heidi Klum and Sandra Bullock just wanted to have fun and spent a Friday night out on the town.

The two women have quite a bit in common: both are single mothers and have experienced painful, public divorces. Bullock adopted her son Louis two years ago, while Klum has four children: Henry, Johan, Leni and Lou. While Bullock divorced Jesse James in 2010 after revelations of his infidelity, Klum is recently single from her split with singer Seal in January.

The pair had dinner at Mr. Chow in Beverly Hills and spent several hours together, talking about everything and just enjoying each other's company, according to reports.

"They were in there for hours," a witness told MSN. The superstars have been friends for years but have never worked together on-screen. Bullock is a film star, while Klum has made her name synonymous with the hit reality series "Project Runway," which is due to return for its 10th season this year.

Both have kept relatively low profiles since their divorces, only speaking out about the positive things in their lives instead of revealing intimate details of their relationships. Neither has been romantically linked with another man but instead seem to be reveling in their single status.

 "I'm a lioness and I have four cubs. I'm a mom. I want to take care of my kids and protect them. I don't want to talk about them, or him, or me," Klum told Elle magazine earlier this month. "With my life, my family, my business-I want to go forward. I feel like already there are so many things being said about us- about him, about me. I'm not going to comment," she added.

Bullock gushed to People last year about her son Louis.

"He's just perfect. I can't even describe him any other way … He has made me a better person. I really appreciate where I am," said the Hollywood star.
