Jennifer Lawrence shades a mystery Hollywood actress during ‘Watch What Happens Live’ appearance

You can always count on Watch What Happens Live! to give us some dirt.

Jennifer Lawrence appeared on the Bravo show on Monday, and got candid alongside her BFF, Laura Simpson.

“Well, the Lady has different variations…the Raging Lady, the Lady in Red, the Lady in Waiting …” Lawrence added, dishing that her and her friends all dislike the unnamed celeb.

However, Lawrence was much less forthcoming about her love life. The Passengers star is reportedly dating 47-year-old director Darren Aronofsky, but when host Andy Cohen asked if she had a boyfriend, Lawrence coyly blew bubbles into her drink.

Later, the avid reality TV fan had some fun with a game of Plead the Fifth, in which she revealed which Real Housewife she would want to be stuck in space with.

“As much as I love Lisa Vanderpump, I think Kyle Richards,” Lawrence mused. “I feel like we would balance each other out a little bit better — a purely survival choice.”
