Ray J's wife flipped off the camera after Zachary Levi joked about the Kim Kardashian West sex tape.
The host of this year's MTV Movie & TV Awards couldn't resist making a quip about the infamous 2007 video at the beginning the ceremony - which aired on Monday night - after he described the rapper turned reality star as "America's other sweetheart".
Complimenting Ray's reality show 'Love & Hip Hop', he joked: "Although I'm sure some of you are more familiar with his work as a cameraman."
While the audience sounded shocked, the camera cut back to Princess who showed both middle fingers to the camera.
Zachary immediately apologised for the quip, and appeared to suggest it won't better in the writer's room.
