Don’t believe the rumors: Ryan Phillippe and Demi Lovato are not dating, PEOPLE has learned.

“This is not true. He’s totally single,” says a source.

Recently, Phillippe has been linked to actress Amanda Seyfriend, however. And while he has never confirmed that he is the father of his ex-girlfriend Alexis Knapp’s baby, the actor, 36, was in the delivery room when the child. a girl named Kai, was born earlier this month.

As for Lovato, who dated singer Joe Jonas for a year starting in 2009 and was recently linked to Wilmer Valderrama, she is not exactly lonely.

Besides promoting her new single and video “Skyscraper,” the 18-year-old has a new puppy.
