Since Beyonce and Jay Z kicked off their On The Run tour, there's only one thing people seem to be talking about — Justin Bieber.

The biggest celebrity feuds

Despite the fact that Bey bared her derriere on stage, the most scandalous moment of the joint tour so far has been some shade Queen Bey threw at Bieber during Jay's performance of "Izzo (H.O.V.A.)." As backdrop for the song, the duo projected an array of celebrity mug shots, including Bieber's, before Beyonce told the crowd "Even the greatest can fall."

Many Beliebers were simply ecstatic that Bey referred to the young singer as one of "the greatest" and it seems he's also taking the situation in stride. The day after the first stop on the On The Run tour, Bieber retweeted a photo of his mug shot on stage.
