Demi Lovato has suggested her relationship with Wilmer Valderrama was "not OK".
The Confident singer was just 18 when she started dating the That 70s Show actor in 2010, when he was 29, and they were together for six years, but now Demi has bonded with fellow former child star Keke Palmer over the relationships they had in their teens which felt grown-up at the time but now they don't think were appropriate.
