Jennifer Lawrence: full-time actress, part-time detective.

Andy Cohen revealed on “Watch What Happens Live” on Tuesday night that the Oscar winner played a key role in helping Bravo track down who leaked audio from the highly anticipated “Summer House” reunion.

“A Bravo superfan provided some crucial information that helped confirm the source,” Cohen said while introducing his Mazel of the day. “Well, with the last reunion episode having aired tonight, I wanted to personally thank that superfan. Folks, that superfan was indeed Jennifer Lawrence … Her online sleuthing helped our team of investigators solve this mystery.”

Cohen added: “Bravo fans are the most loyal and dedicated. Jennifer Lawrence, Oscar winner, you were the top of the class!”

The “Summer House” leak happened in April after the news came out that stars Amanda Batula and West Wilson had started dating. Batula was previously married to Wilson’s friend, Kyle Cooke, while Wilson had an on-and-off relationship with Batula’s best friend, Ciara Miller. The leak enraged fans, who mobilized to try and find the source.
