Fans turning up for the Britney Spears and Madonna reunion would have been expecting to see the 26-year-old in a typically raunchy outfit.
But instead the 50-year-old Material Girl was the one wearing the more revealing clothes as the pair performed a duet on stage.
The pop megastars looked like they should have swapped outfits as they sang together at the Dodger Stadium in Los Angeles during Madonna's Sticky and Sweet tour.

A demure looking Britney, dressed in a simple white blouse and black trousers was invited on stage by Madonna and joined in with one of her songs.
And Madonna was also joined by Justin Timberlake to join in with another of her hits.
Rumours that the former couple, who split in 2002, would perform together with Madonna proved unfounded though as they did not appear together on stage.

It's a bit different from the last time Britney and Madonna appeared on stage together.

It's not the first they have collaborated together, with Madonna appearing on Britney's track 'Me Against the Music' on her In The Zone album.
