Rumors are starting to circulate once again around Robert Pattinson moving on from Kristen Stewart with pop star Katy Perry.

Reporters Ask Robert Pattinson About His Relationship Status?

On Wednesday, Radar Online reported that the Twilight star and the Birthday singer were "all over each other" during the premiere of the actor's latest film The Rover.

"Rob was his usual charming self, greeting a solid wall of fans on the red carpet," a source said.

Kristen Stewart Finds Happiness Again?

Apparently, the actor decided to skip out on the movie screening and partied with Perry at the W Hotel.

"When Rob saw Katy his eyes lit up," the source said. "She looked gorgeous in a lace sequin black mini-dress, and they hugged and kissed."

The actor reportedly could have spent time with a number of other attractive females at the party, but he allegedly used that time only on the Hot N Cold singer.

"At least 10 hotties were hovering around Rob, but his focus was on Katy," the source said.

"He kept kissing her the entire night," the insider added.

The site then mentioned that the two were trying to make their night together under a low profile, but their feelings may have gotten the best of them.

"When Katy got up from a sofa that was in front of a fireplace, Robert walked over to her," the insider said. "They kissed and hugged again. They were clearly trying to stay under the radar, but they couldn't help showing their feelings."
