And we bet he's hoping she liked it!

The 24-year-old singer reportedly locked lips with MTV VMAs host Russell Brand at an after-party.

A source said:

"They were sitting very close together, flirting and whispering to each other with their faces very close.  Then Russell leaned in for a long kiss."

Adding: 

"It didn't look like this was the first time. He was looking extremely pleased with himself."

As he well should!

Perry was bustin' out before the show in a silver mini-dress adorned with spikes.

Sexy mama!
