Demi Lovato's Halloween Party with Wilmer Valderrama

Getting into the autumn spirit, Demi Lovato attended a Halloween party in Los Angeles over the weekend.

And it seems the shindig brought the “Skyscraper” songstress back in touch with her famous ex-boyfriend Wilmer Valderrama.

Demi and Wilmer, who broke up this past June, appeared in a picture taken at the event, and television producer Billy Clarke tweeted about seeing them both at the bash.

Clarke wrote, “Great seein yall 2nite @Willyville @ddlovato. Will, Lets get up this week budd. DL, didnt get 2 say bye & take care of my girl @ShariShort11.”
