Miley Cyrus was caught on camera kissing one of Britney Spears' female backing dancers at the opening night of her Las Vegas residency.

As previously reported, the 'Wrecking Ball' star attended the first night of Spears' two-year Planet Hollywood residency last night (December 27).

She was spotted dancing along to the music in the front row of the gig, which saw Spears run through a host of hits.

However, video footage has emerged of Cyrus stepping out of her seat and dancing seductively with two of Spears' dancers.

She then kissed one of them before sitting back in her seat.

Spears meanwhile reached out to Cyrus on Twitter post-show, saying: "Love you so much! Thank you for coming to #PieceOfMe! I adore you :)."
