After weeks of speculation, Life & Style can exclusively reveal that Rebecca Gayheart and Eric Dane are expecting their second child together!

"She's glowing -- and so happy," a friend tells Life & Style. "They wanted to add another child to their family, and now they've got that! They're in a real good place."

The former Beverly Hills, 90210 star, 39, and Grey's Anatomy actor, 38, tied the knot in October 2004 and welcomed their first daughter, Billie Beatrice, in March 2010.

Reps could not be reached for comment.

Congratulations to the happy couple!
