If you thought she was tough to deal with on the tennis court…you were right. But it might be even more unpleasant to be subjected to Serena Williams‘ vocal stylings than her serve.

In NYC, a week before the U.S. Open kicks off, Williams took to a club for a sponsored pre-party with fellow tennis player Jack Sock, Glee‘s Darren Criss, and Orange Is the New Black‘s Laverne Cox and Uzo Adubo. Williams took on “Diamonds Are a Girl’s Best Friend,” and while she wasn’t great, she also wasn’t bad enough to be entertaining—you know, like 50 Cent-opening-pitch bad.

Here’s the video, so you can play Simon Cowell to her William Hung:

Big ups to Delta Airlines for making all this possible.

They love to fly (and it shows). Hopefully she’ll save some showmanship for the opening rounds of next week’s US Open, where she’ll probably wipe the floor with her competitors in the opening rounds.
