The Bangerz beauty was front row and center at Brit's Piece of Me Concert in Las Vegas on Dec. 28. But Miley girl wasn't just watching her fellow Southern superstar perform—she was dancing, singing along and fangirling adorably, even sitting beside Brit's mom Lynne and sister Jamie Lynn Spears!
"if u told me I'd be front row & center on @britneyspears opening night 10 years ago I wouldve never believed you," Miley tweeted, along with a tongue-out, thumbs-up picture of herself at the show. Fan Instagram videos show M.C.'s inner-tween coming out full force as her pop idol breaks it down onstage. She can also be spotted holding what appears to be a beer (not to worry, y'all—she's 21!).
Britney, 32, was thrilled that the Queen of Twerk came out to her opening show. ".@MileyCyrus Love you so much!" she tweeted. "Thank you for coming to #PieceOfMe! I adore you :)."
AWW! The feeling, clearly, is mutual. In July, Miley told the Huffington Post U.K. why she relates to Brit so much, saying, "Everyone goes through a time in their life where they don't want their picture taken everyday…She just never had that time where she could say, 'I'm going through something right now and need to shut down.' I also don't have that, so it's good to have that one person in my life who gets it."
"I just think it's never blaming you or making you feel like, ‘You've got all this going for you,' it's like she knows," she said. "Sometimes life just steps in the middle of your career the way life always does for anyone—it's just ours is a little more 24/7."
Well, it helps to have BFFs in the biz—especially ones like Brit!
