Demi Lovato Hooking Up With Ryan Phillippe?

Ryan Phillippe was spotted doing the walk of shame from Demi Lovato's house in the early hours of Sunday morning.

The 43-year-old actor, who briefly dated the pop star in 2011, kept a low profile as he was photographed arriving late at Demi's Halloween party at around midnight and then leaving at 5am.

Eyewitnesses report the Shooter star turned up to Demi's LA home when guests had left the singer's Haunted Carnival Bash.
