Jennifer Garner and Violet Affleck enjoy a day at Jonathan Beach Club, Santa Monica, California - 22.07.08

The actress, who is expecting a second child with husband Ben Affleck, poses seductively in a plunging little black dress in the new ads for an energy renewal night cream.

And the wannabe naughty girl says, "Every girl has a past when she did some things that maybe she shouldn't, but I say, 'No one ever has to know.'"

But the former Alias star adds coyly, "Me a bad girl, never!"
