Oh, baby! Check out Ben's sexy sitter

Why did Ben Affleck announce that he was "going home to make love to the babysitter," after getting a Supporting Actor of the Year honor at the Hollywood Awards?

Duh.

The "babysitter" was none other than his wife Jennifer Garner, who walked the red carpet with him but then left to look after their daughter.

One look at Jen in this sexy bronze Gucci goddess gown explains Ben's mad rush.

Bet she'll be a great accessory during her hubby's Best Supporting Actor Oscar nomination campaign for his portrayal of George Reeves in "Hollywoodland."
