The 27-year-old actor ended his four year romance with Stewart in May this year and has no plans to hook up with someone else, reported Showbizspy.
"Rob has absolutely no interest in dating anyone right now. His number one priority is music and movies. Rob likes to flirt, but remember he has women throwing themselves on him all the time. He enjoys all of the attention, but doesn't take any of it too seriously," a source said.
"He has not spoken to Kristen for quite some time now. Work is keeping them both very busy. There is no one special girl in his life. As for Kristen, they don't talk, they have separate lives," it added.
