She's just being J-Law. Jennifer Lawrence was her usual blend of gorgeous, wacky and lovably inappropriate on the red carpet outside L.A.'s Shrine Auditorium for the SAG Awards 2014 Saturday. Wearing a much-different look than her talked-about Golden Globes look last Sunday, the actress, 23, nevertheless wore another design by Dior -- this one a strapless sequined number. But the Kentucky native claimed to Giuliani Rancic that the form-fitting number was slightly too small for her figure. As she hiked up the top of the gown, the American Hustle star complained of "armpit fat -- it's awful" (Giuliana quickly protested that Lawrence had no such "fat" to speak of.)

"Great," Lawrence said. "Now you can maybe look at my armpit vagina. All these cameras, it's horrible!"

After uttering that "armpit vagina" phrase a couple more times, Lawrence went on to explain last Sunday's most talked-about carpet moment at the Globes: Lawrence's Taylor Swift photo bomb! "U didn't' think there was a wide camera," she told Rancic. "I was joking with you guys. i didn't think you guys got it on live camera!"

Once Rancic grabbed the camera man apparently responsible for capturing Lawrence's hilarious angry sneaky expression ascending the stair behind Swift, she yelled, "I do blame you!"
