P Diddy's 50th birthday bash was entirely star-studded, with a guest list that included Kim Kardashian, Cardi B, Leonardo DiCaprio , Jay Z and Beyonce.
And while the A-listers in attendance enjoyed themselves, there was one moment that had Jay holding up.
When the rapper spotted a man trying to stealthily film his wife Beyonce dancing, he wasn't pleased.
Footage shows Queen B boogying to Bobby Brown's song 'Every Little Step' with her pals, former Destiny's Child member Kelly Rowland and rapper Saweetie.
When Jay Z saw a man standing next to his wife with his phone out, snatched the phone after giving him what appears to be a verbal warning.
Fan accounts quickly picked up the tense dance floor moment, sharing video footage on Instagram.
Looks like that man will find himself saying sorry soon enough.
In typical Beyonce fashion, the pop icon shared plenty of pictures from the bash, showcasing her glamorous black gown as well as photos of her husband and P Diddy.
