Blake Lively and hubby Ryan Reynolds have got that lovin' feelin'!

A pregnant Blake showed off her growing baby bump at the Gabrielle's Angel Ball in New York, on Monday night, wearing a tight, pale yellow dress with plunging, jeweled neckline -- highlighting her awesome pregnancy cleavage and her adorable belly.

The couple celebrated their two-year anniversary just last month -- so it seems the pair are wasting little time getting a start on the big family they've both said they want.

Ryan recently told Canada's eTalk what he's thinking of for baby names: "On the plane over here I was trying to think of baby names. I don't want a name that's anything pretentious or, like, Hollywood-y. So I'm going with Excalibur Anaconda Reynolds…that's if it's a girl." When asked what he'd name a boy -- "Bruce Jenner," the actor laughed.

We can't WAIT to hear what they really choose ... and to see what this child, with amazing genes, will look like!
