Maybe not yet, but the Grey's Anatomy star is the subject of such speculation after a romantic stay at the San Ysidro Ranch in Montecito, Calif., on August 21.

How could Eric Dane and Rebecca Gayheart be so lighthearted after the release of what could be a career-killing sex tape (or just naked tape) last week?

Because they may be expecting a little McSteamy!

Or at least trying for one.

"Having a baby has been a top priority of the past six months," reveals a friend of the couple.

Another source says that Rebecca, 38, and Grey's Anatomy hunk Eric, 36, have actually had trouble conceiving since they eloped to Las Vegas in 2004.

Some sources say Rebecca's finally 3-4 months pregnant. While we're hesitant to believe that, the couple is said to be trying harder than ever to have kids.

"She turned down a role on Gossip Girl because she didn't want to be away from Eric or travel that far. It was bad for her health," the insider says. "She also turned down a Hallmark movie and a Lifetime movie because she is trying to have a baby."
