Things have been quiet on the Katy Perry romance front recently, since she was initially linked to dance music superstar Diplo.

But now the 29-year-old pop princess has been sighted hanging out in the VIP area at one of his club gigs in Las Vegas.

People reports that she was seen sipping water and nodding her head to his set at the Surrender Nightclub in Encore at Wynn Las Vegas.

And here's the killer blow - she apparently left as he finished playing, while he followed shortly after at 3.15am.

Case closed your honour!
