Backstreet Boys appeared to have been inspired by Miley Cyrus when they showed off their twerking skills at the launch of their UK tour.
Nick Carter, Brian Littrell, AJ McLean, Howie Dorough and Kevin Richardson were back in style at the Birmingham NEC, performing 18 songs to a crowd of mostly middle aged women and teenage boys, according to The Daily Mirror.
The reformed 90s boyband added twerking to their dance routines, with all the lads shaking their behinds along to the beat.
And Nick had the ladies screaming when he donned a bright green G-String to twerk in.
The boys took a break from dancing and sat down for an acoustic performance half way through the show. But they still belted out all their hits including As Long As You Love Me, I'll Never. Break Your Heart, We've Got It Going On, I Want It That Way and Everybody (Backstreet's Back).
The crowd had been warmed up by All Saints who sang hits including Pure Shores, Black Coffee and Never Ever.
