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.

However, a spokesperson for Lovato said, "She has never asked Ryan for any help, nor does she expect it."
