With the explosive news breaking that Sandra Bullock has filed for divorce from her cheating husband, Jesse James, and has adopted a baby boy from New Orleans, GOSSIP has learned that even James’ mistresses are happy for the new mother.

“I think it’s really great for Sandra because I think she’s had a rough time lately,” Merilee Gerth tells RadarOnline.com exclusively. “She’s a really nice person and I’m really happy for her. She deserves it.”

As RadarOnline.com previously reported, Gerth carried on a sexual relationship with James that ended in 2007 when Gerth filed a sexual harassment lawsuit that was eventually settled out of court for a large six figure sum. Gerth kept a shirt with James’ DNA on it as the ‘smoking gun’ to prove their relationship together.

“I don’t remember ever hearing Jesse talk about the adoption,” Gerth told RadarOnline.com Wednesday morning. “I hope Sandra has a really happy life with her new baby.”

Bullock adopted a 3-and-a-half-month-old African-American baby boy from New Orleans that she named Louis Bardo Bullock. She originally began the adoption process with James four years ago, but last week Bullock filed divorce papers in Austin, Texas. She says she will be adopting as a single parent.
