James Marsden Expecting A Baby With Model Rose Costa After Brief Courtship

It seems that one night really can lead to forever. "X-Men" and "30 Rock" actor James Marsden is reportedly expecting a baby with Brazilian model Rose Costa after spending a night with her in Miami. 

Marsden just recently finalized his divorce from his wife of 11 years, Lisa Linde, who the actor has two children with and Costa was dating LA-based actor Chris Santos, who is said to be "heartbroken."

"She confessed everything," a source told the New York Post. "She told him they hooked up one night, one time,"

Immediately after Costa's confession the source added that Santos moved out.

Marsden and Costa began dating last fall when she moved to New York from Los Angeles to pursue modeling. She was allegedly still dating Santos at the time.

"Santos found out and flew to New York to win her back," a source told the New York Post. "They spent the holidays together and got a new apartment."

However, Costa had to fly back to Miami to renew her Visa and ran into Marsden while she was out there. A month after that night Costa called Marsden to tell him she is pregnant. Costa is reportedly three months along and is planning on keeping the baby.

Reps for Santos and Costa had no comment for the New York Post and a rep for Marsden couldn't be reached by the newspaper.
