OMG! A pregnancy on the "Gossip Girl" set?

OMG!  A "Gossip Girl" is preggers?

Relax, its  not Serena (Blake Lively) or Blair (Leighton Meester) or even Little J (Taylor Momsen).

At least, not yet

Us is reporting that Kelly Rutherford, who plays Blake Lively's mother, Lilly van Der Woodsen, is expecting her second child in June in real life.

She and her husband Daniel Giersch already have a  two-year-old son named Hermes, who, according to Us, likes to hang out on the set.

Hermes. Hmm. Is it pronounced like the speedy Roman messenger god or the French luxury brand?.

Wonder how - or if - this pregnancy will figure into the "Gossip Girl" scenerio?

Will there be a bun in Lilly's oven on the show?

And who should be the Baby Daddy: Bart Bass or Rufus Humphrey?

We're voting for Rufus.
