(CBS News) James Marsden is gearing up to be a dad, again.

Pictures: Celebrities who are expecting

The "X-Men" star is expecting a baby with a model, whom he briefly dated after he split from his wife, reports People.

The New York Post is identifying the woman as 24-year-old Brazilian model Rose Costa.

The actor, who played Tina Fey's boyfriend on "30 Rock" last season, split from his wife of 11 years, Lisa Linde, in September. Linde filed for divorce citing irreconcilable differences. A rep for Marsden, 38, said it was a "mutual decision." Marsden has two children with Linde: Jack and Mary.

The actor was in Hawaii last week at the Maui Film Festival promoting his new film with Kirsten Dunst, "Bachelorette." He was also honored with the Nova Award, reports E! News.
