[photogallerylink id=26079 align=left] If you were at the [lastfm link_type="artist_info"]Britney Spears[/lastfm] show last week at the Power Balance Pavilion, you saw her opening act [lastfm link_type="artist_info"]Nicki Minaj[/lastfm] too (who ran about 10 minutes over her time). Well, I just saw a report saying that at Saturday’s Femme  Fatale stop in the bay, Nicki  ran over her time by about 45 minutes… and Britney was ticked off!

MediaTakeOut.com is reporting that drama happened backstage at Britney’s show over the weekend!

“According to a member of Nicki Minaj’s camp, Nicki and Britney Spears have been BUTTING HEADS during their FEMME FATALE tour . . . and on Saturday night . . . it POPPED OFF!”

The insider, who has been a TRUSTED MediaTakeOut.com INFORMANT in the past tells us, “Britney is upset that Nicki kept running over her allotted time. In Sacramento she was over about 10 minutes. But on Saturday night in San Jose Nicki went over by nearly 45 minutes.”

They are reporting that “Britney came by Nicki’s dressing room with her dancers. That were trash talking Nicki very loudly right outside of her dressing room. Nicki heard what they were saying and came flying out of her dressing room ready to fight. But when she saw how RIDICULOUS Britney and her crew looked, she just laughed.”

Britney and Nicki JUST started their tour together so they are stuck with each other for the next couple of months! Maybe Enrique Iglesias knew exactly what he was doing when he bailed on this tour?!
