She's baaaaack!

Miley Cyrus performed at London's O2 Arena on Tuesday night, and after a three week hiatus from her Bangerz tour, she was back to her usual tricks when she took the stage.

A source told The Daily Mail that Miley was "drinking water and spitting it on the crowd" and asking people to make out with members of the same sex. While none of that is a total shock, the concert-goer added, "She said she 'hopes we are all drunk and on loads of pills,' and at one point her dressers had to come on stage as her corset was undone."

After postponing a handful of her U.S. tour dates last month due to an allergic reaction to antibiotics, Miley was forced to cancel her concerts in Amsterdam and Belgium last week as well, and while we get that Miley is excited to be back on the road, maybe she should avoid the drug references?

Especially after telling reporters earlier in the day that she's the "poster child for good health"...
