The rumour mill is churning out another Demi Lovato/Wilmer Valderrama tale.

Apparently, the 20-year-old singer and the 33-year-old actor (who dated back in 2010) spend Valentine’s Day together, and even engaged in a little snuggling.

“They ordered almost everything on the menu, but they didn’t touch it for at least an hour,” a source said, reports ShowbizSpy.

“They stared into each other’s eyes the whole time.”
