No wonder Demi Lovato is in need of treatment.
A new story in The New York Post says the young singer was dating serial celebrity banger Wilmer Valderrama immediately prior to checking into rehab last month. The two reportedly first connected when they filmed a public-service spot together in Chile for earthquake relief in March.
"The two started seeing each other in May right after her breakup with Joe Jonas," a tour source told the newspaper. "She would show us pictures of them together."
Valderrama has dated around... A LOT.
He claims to have swpied Mandy Moore's virginity, done the nasty with Lindsay Lohan, referred to Ashlee Simpson as being loud in bed and rated Jennifer Love Hewitt as an eight out of 10.
** UPDATE: A rep for Valderrama says this report is "false."
