Apparently, Selena Gomez can’t keep her hands to herself and Orlando Bloom’s current girlfriend, Katy Perry is not happy about it. So what is the “Firework” hit maker’s reaction about the duo’s PDA session in Las Vegas?

“Katy is leaning towards trusting Orlando and is thinking that he did nothing wrong, even though the pictures appear to show something different,” a source told Hollywood Life.“She is currently more pissed at Selena and wants her to stay away from Orlando at all costs.”

The insider then went on to say that Katy Perry doesn’t trust Gomez, saying that “She is still looking to find out exactly what happened and has a lot more questions than answers right now. Things are pretty tense and can turn on a dime, but her mindset is currently putting blame on Selena.”

In photos obtained by TMZ, the 23-year-old “Same Old Love” singer and the 39-year-old “Pirates of the Caribbean” actor will be seen getting cosy at a Las Vegas nightclub on Saturday, May 7, looking very much like a couple.

While Orlando was getting physical with Gomez, Katy Perry took to Twitter on Sunday, May 8, and gush over how she was looking forward to spending her life with him.

“What’s the cut off age of being able to say ‘I want to grow old with you?’ Like, 50? 65? 31?” she tweeted.

While the photos may appear suspicious, E! News reports that Katy Perry has nothing to worry about as the two stars were not hitting the Vegas clubs together. Gomez was hosting the official after-party for her “Revival” tour at LIGHT at Mandalay Bay while Bloom also happened to be there for a friend’s bachelor party.

Romance rumours have followed Gomez and Bloom for years, reports Entertainment Tonight, but reps of the duo have always insisted that they are just good friends since they have the same manager.
