Hollywood's recent baby boom just gained a little more momentum from actress Selma Blair. The 38-year-old 'Hellboy' actress is reportedly "ecstatic" about the unexpected news.

A source tells Star magazine that Selma and her boyfriend of less than a year, fashion designer Jason Bleick, have no immediate plans to wed. Selma was married to musician Frank Zappa's son Ahmet from 2004 to 2006.

The source continues that Selma "never thought she could be this happy." The actress has yet to release a statement about her pregnancy, and no details of the due date have been disclosed.

Selma has had a long and steadily successful career in film and television, and is a rare star who has managed to stay out of the tabloids. She played 'Kim' alongside comedian Molly Shannon in NBC's short lived remake of the Australian sitcom 'Kath & Kim.' Many remember her for her part in the 1999 drama 'Cruel Intentions,' where she starred alongside Reese Witherspoon, Sarah Michelle Gellar and Ryan Phillippe.

Selma's baby will have lots of playmates in tinsel town. Actors Owen Wilson, Kate Hudson and Marion Cotillard are also expecting.
