Valderrama: 'I'm not dating Demi Lovato'

Wilmer Valderrama has dismissed speculation suggesting that he is dating Demi Lovato.

It was reported earlier today that the That '70s Show star and Lovato began seeing each other after she broke up with Joe Jonas.

According to the claims, the pair met in Chile where they filmed a public service announcement to benefit earthquake relief efforts.

However, Valderrama's representative has denied the rumours, telling Gossip Cop that the reports are "not true".

Lovato recently checked into rehab to deal with personal issues.
