Jay-Z got in a man's face and snatched his cell phone for filming Beyonce at Sean Combs' star-studded 50th birthday party on Saturday.

The couple was among the many well-heeled guests helping their pal celebrate his big day at his Los Angeles mansion.

In footage filmed by a guest at the bash, the 39-year-old "Formation" singer can be seen getting down to Bobby Brown's classic hit "Every Little Step" alongside her pals Kelly Rowland and rapper Saweetie. Her overly protective husband hovered nearby.

The 50-year-old rapper quickly sprung to action when he caught a male guest standing right next to Beyonce with his cell phone out, seemingly trying to film the semi-retired singer.

In a second clip, the "Big Pimpin" rapper snatched the phone out of the stunned partygoer's hand. However, he appeared to return the phone swiftly after warning the reveler against recording his wife again.

The dreadlocked rapper can be heard asking the man, "Who invited you?"

The incident apparently didn't faze Beyonce, as the "Run The World (Girls)" star seemed to be in her own world.

The big night also saw Jay reunite with Kanye West, three years after the "Power" hitmaker called out Jay-Z and Beyonce onstage for skipping his 2014 wedding to wife Kim Kardashian-West.
