Just a few months ago, Wilmer Valderrama and Demi Lovato ended their long-term relationship in friendly fashion.
But now the actor has been spotted VERY friendly with one of his famous ex-girlfriends...
... if you know what we mean!
An insider has confirmed to E! News that Valderrama and Kelly, who split back in 2012, spent Labor Day Weekend in Mexico together.
No one else joined them on the trip and the former lovers appeared to be picking things right back up after over four years apart.
In one paparazzi photo, Valderrama is drying off with a towel, while Kelly wearing a baseball cap and chilling under an umbrella.
The vacation took place a after days after the actor and actress were spotted at Palms Thai restaurant in Hollywood last Wednesday.
An onlooker told E! News that the stars looked quite cozy and close close during their time out, adding that Valderrama was a total gentleman, opening the car door for his date and paying for the meal.
"They sat across from each other and it was just the two of them," this witness said.
"I didn't personally see if they were holding hands or if they were being affectionate, but it looked like a date. They looked casual and relaxed."
Based on these reports, E! News writes that Valderrama and Kelly have "reconciled their romance and are officially dating again."
Poor Demi Lovato, huh?
In early June, she and Valderrama released a joint statement that reads as follows:
"This was an incredibly difficult decision for both of us, but we have realized more than anything that we are better as best friends.
"We will always be supportive of one another. Thank you to everyone who has offered us kindness and support over the years."
These two had seemed like one of the happiest, most stable couple in Hollywood.
But sources claimed the romance had turned into almost more of a sibling type of relationship, with Valderrama feeling like he was more akin to Demi's big brother than her boyfriend.
How is she reacting to the news of her ex getting back together with one of his exes?
We have no idea, but Lovato did Tweet the following on Saturday:
You have to be capable of being honest with yourself before you can get honest with other people.
Might this have been a reference to Valderrama?
No one can blame Demi if she's bitter, can they?
After dating someone for many years, seeing them with someone else is heartbreaking.
But seeing them with someone else they had dated before you? Just a few months after your split? Who is as attractive as Kelly?
We feel for you, Demi. Hang in there.
