Jennifer Lawrence attended the premiere of Serena at the BFI London Film Festival on Monday night, and the 24-year-old starlet seemingly wore a long blazer ... and not much else! Is there a dress under there? Or even a skirt? I mean, she looks great, but after going bra-less last week at a photo shoot, you'd think J. Law might want to cover up her tatas, but apparently not!

Lawrence's boobs were out on the recent cover of Vanity Fair, and the Oscar winner opened up about her recent nude photo scandal. "Just because I’m a public figure, just because I’m an actress, does not mean that I asked for this," she said of her X-rated pics being leaked online. "It does not mean that it comes with the territory. It’s my body, and it should be my choice, and the fact that it is not my choice is absolutely disgusting. I can’t believe that we even live in that kind of world."

While we see her point, we also feel like it might have sounded a bit more sincere if she wasn't topless in her spread for the mag. Still, it's her body, and she's choosing when and where she wants to show it off, so we get that too. But does she wear stuff this sexy for boyfriend Chris Martin?

Speaking of Chris, he recently met Jen's mom, and not only is he now parent-approved, but he has an invite to Christmas dinner! Jennifer's grandmother, Carolyn Kloch, reportedly told The Sun, "Jennifer's mum flew to Los Angeles to meet Chris. We will have to get another chair for the dinner table at Christmas! The family is getting so big we might have to split up for gatherings."

Jen's probably not stoked about granny spilling the beans, but she's gotta be happy about how serious things have gotten with her much older beau!
