AceShowbiz - Even though rumors have been swirling that Wilmer Valderrama is rekindling his romance with Demi Lovato, the report may not be true. The "Grey's Anatomy" actor was seen hanging out with a mystery woman in Calabasas on Saturday night, August 11.

A photo from the outing has been circulating online, showing the twosome walking out of a restaurant in the city. Wilmer sported a long-sleeved shirt and a dark green pants for the night out, while his brunette friend opted for a white tank top and a pair of jeans. She completed her look with a wide-brim hat and appeared to be carrying a black handbag.

However, it's still unclear whether or not the outing is a date.

Rumors of Wilmer and Demi going back together first sparked after a source revealed that her recent overdose "brought her and Wilmer back together." In addition, the Disney alum was allegedly head over heels for the actor that marriage is not out of the question. It was said that "Wilmer feels the same way - he wants to get married, too."

Recently, a new report suggested that the "From Dusk Till Dawn" star had been keeping in touch with her after she checked herself into a rehab facility. "Wilmer is continuing to support her and has been actively following up and checking in on her when he can," an insider told Us Weekly.

According to the source, the former couple still had feelings for each other after their split in 2016. Wilmer reportedly "has made it a priority and they've never fallen out of love." The insider added, "Even though they are broken up and not together right now, when a loved one goes through a crisis, your true colors of who you are as a person come out and he has really portrayed himself in the same way that she's spoken about him in all of her previous public interviews."
