(Cover) - EN Showbiz - Demi Lovato is reportedly back with her ex-boyfriend Wilmer Valderrama.

The pair ignited rumours that they have rekindled their romance after they were seen kissing on the streets of Los Angeles yesterday.

The 19-year-old performer broke up with singer Joe Jonas back in 2010 and was linked to Wilmer soon after.

She sought treatment for an eating disorder and other issues at a rehab facility later that year and has bounced back with new music and a resurgence in her career in recent months.

Demi and Wilmer, 31, were photographed in a deep embrace and seemed very loved up together outside his house but her representatives are not giving any more details.

"We're not going to comment on this," Demi's spokesperson told People magazine.

The pair also attended a Halloween party together on Monday night, TMZ reported.

Wilmer has been linked to Lindsay Lohan, Ashlee Simpson, Mila Kunis and Jennifer Love Hewitt in the past. (C) Cover Media
