Jennifer Lawrence never fails to inject some humor whenever she steps on the red carpet.

During the Screen Actors' Guild Awards last Saturday, the "American Hustle" actress appeared in the red carpet wearing a sequined navy blue dress by, again, Dior. But she revealed to Giuliana Rancic of E! News that the gown she's wearing is slightly too small for her as she was caught hiking up her dress and complaining of her 'awful' armpit fat.

To which Rancic protests with, 'Who doesn't have armpit fat?'

Lawrence then replies, "Great, now you can maybe look at my armpit vagina."

Despite the "armpit vagina," various commentators commended how she looked good in the dress. Huffington Post even consoled her by saying, "It's cool, J.Law -- we're all insecure about something. And your dress looked amazing."

Meanwhile, she recounts to Rancic how she admires Charlize Theron and other actors when she was younger.

"I remember watching Charlize Theron when I was really young. She's incredible," says Lawrence. "I love Sean Penn very much... Tommy Lee Jones... I could go on forever."

Then she went on to talk about her memorable photobomb on Taylor Swift during the Golden Globes.

"I 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!"

"I didn't know it until my friend texted me that picture that night!" exclaims Lawrence.

And when Rancic points out to the cameraman responsible for the photobomb shot, Lawrence tells him, "I do blame you!"

Lawrence loses to Lupita Nyong'o for the Outstanding Performance by a Female Actor in a Supporting Role award in the Screen Actors' Guild. However, the entire cast of "American Hustle" won the Outstanding Performance by a Cast in a Motion Picture award.

She has previously bagged the Best Supporting Actress award during the Golden Globes, and she was also nominated for the same category in the upcoming Academy Awards.
