Britney Spears' opens her Las Vegas residency with storming 90-minute trip down memory lane

With seven costume changes, two wig changes, 23 hit singles and one auditorium filled to the rafters with adoring fans, Britney Spears kicked off her Las Vegas residency on Friday evening – in a set that lasted for a mere 90-minutes.
The singer was on stage at the Planet Hollywood Resort & Casino for the first of 100 lucrative shows at the venue after agreeing to the Piece Of Me residency at the Nevada gambling mecca earlier this year.
Celebrity fans Miley Cyrus, Katy Perry and Adam Lambert were in attendance as she turned in a comprehensive performance that provided fans with a retrospective look back at her convoluted pop history.
