Demi Lovato recently stepped out with her new blue locks. But it seems the aqua hair isn’t the only accessory she’s sporting these days.

It appears Lovato is back with ex-boyfriend, Wilmer Valderrama. The two were spotted holding hands this weekend at Knott’s Berry Farm’s Halloween Haunt.

But what’s even more interesting is that it appeared Lovato was trying to stay incognito. The singer and X-Factor judge was clad in black garments from head-to-toe. She even buried her new ‘do underneath the hood of her baggy shirt. While actor and funny-man Valderrama kept it casual in a simple jeans and t-shirt combo.

Was Lovato just being shy from the paparazzi or is she not certain of the two reuniting?

While Lovato might be hiding from the flash of the cameras, she wasn’t about to ditch her buds. Lovato and Valderrama showed up to the park with a pack of friends, enjoying the festivities and roller coasters.

Apparently this isn’t the first time the two have been seen post-breakup. They cozied up together in August at Disneyland Resort.

While the officialness of their relationship is up in the air, what is clear is the two enjoy theme parks.
