Britney Spears kicked off her Las Vegas residency in style over the weekend and Miley Cyrus was there to see the whole thing. Of course she was. Never one to miss an important moment is Miley.

The Wrecking Ball singer revealed that she loves Britters just as much as we do, gyrating in the front row as the pop songstress did her 'thang' and errr, mimed a selection of her biggest and best tunes if the US tabloids are to be believed. Sure would you look at Hannah Montana go?

Of course Miley wasn't the only one in the audience, with Selena Gomez dancing the night away alongside Katy Perry's stylist Johnny Wujek. Speaking of Katy though, she seemed less than impressed, opting to scratch her head while Selena and Johnny were on their feet.

Guess Ms Spears just didn't drive her crazy this time around.
