Demi Lovato dated Ryan Phillippe

Demi Lovato has reportedly been dating Ryan Phillippe. The 18-year-old singer and actress is said to have been seeing The Lincoln Lawyer actor in the last few months, but things cooled since he became a father with his ex-girlfriend, Alexis Knapp, two weeks ago.

“It was really hot and heavy for a while,” a source said.

The insider added Demi wasn’t aware Ryan, 36, was to become a father for the third time “until it basically happened. It kind of threw her for a loop.”

Ryan — who also has two children, Ava Elizabeth, 11, and Deacon Reese, seven, with ex-wife Reese Witherspoon — was with Alexis Knapp when she gave birth to a daughter, who she has named Kai. He also had an on/off relationship with actress Amanda Seyfried earlier this year.
