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.

After the leaker was discovered, Bravo released a statement and confirmed that the perpetrator had been fired. “An investigation into the recent leak of the ‘Summer House’ reunion audio has concluded that the audio was an unauthorized recording and distributed by an individual involved in the production of the reunion,” the network said. “As a result of the findings, appropriate action has been taken. There is no evidence that any member of the cast was involved in the recording of the audio.”

Lawrence has long been a Bravo fan, often appearing on “Watch What Happens Live” and sharing her love for the “Real Housewives” franchise. While speaking to Variety at Toronto Film Festival in 2022, Lawrence went off on “Real Housewives of Beverly Hills” star Erika Jayne, who was in the middle of an embezzlement scandal with her then-husband Tom Girardi.

“My biggest problem with this season is that it’s just been boring and I think that Erika is evil,” Lawrence said. “I would go as far as to say, she needs a publicist ASAP.”
