Los Angeles: Actress Demi Lovato is reportedly dating actor Ryan Phillippe. The 18-year-old singer-actress has been seeing Phillippe for the past few months, but things took a backseat when his ex-girlfriend Alexis Knapp gave birth to his child two weeks ago. “It was really hot and heavy for a while,” a source told E! News, but added that Lovato wasn’t aware that the actor was to become a father for the third time “until it basically happened. It kind of threw her for a loop.” Phillippe, who also has two children, Ava Elizabeth, 11, and Deacon Reese, seven, with ex-wife Reese Witherspoon, was with Alexis when she gave birth to their daughter Kai.
