Orlando Bloom and Selena Gomez get up close and personal – behind Katy Perry's back

THESE Hollywood romances are getting way too confusing for us.

CAUGHT IN THE ACT? Pictures suggest the pair could be more than just friends

Just when we thought Orlando Bloom was settling down with Katy Perry, he's been spotted getting very cosy with Selena Gomez in a Las Vegas nightclub.

TMZ obtained pics of the pair getting very touchy-feely with each other.

Orlando, 39, can be seen nuzzling Selena's neck and although it can't be confirmed, it looks like the 23-year-old songstress sneaks a kiss from the Hollywood actor.

Clearly Selena can't keep her hands to herself.

NEW ROMANCE? Is Selena hooking up with Orlando?

Despite the public displays of affection, TMZ reports that Selena went back to her room alone on Saturday night.

The Lord of the Rings actor was spotted with Katy Perry just last week at the Met Gala and the Twittersphere is swirling with rumours that he's cheating on the outrageous pop star.

So are Sel-ando going to be an actual thing?

They've been pals for a few years now and were forced to deny they were a couple after being spotted together at a concert in 2014.
