Demi Lovato posted a strange tweet on Friday, that appears to be a shot at her ex-boyfriend Wilmer Valderrama — a day after a source confirmed Valderrama was dating actress Minka Kelly once again.

Demi Lovato Tweets After Valderrama & Kelly Dating News

Valderrama and Kelly first dated back in 2012, after Kelly ended her relationship with baseball star Derek Jeter.

The pair have reportedly renewed their romance — sources revealed that Valderrama and Kelly enjoyed a Mexican vacation earlier this month and the couple were spotted stepping out together for dinner at a Thai restaurant in Hollywood on Thursday.

“[Minka and Wilmer] did have a late dinner at Palms Thai together last night. They sat across from each other and it was just the two of them. 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,” an insider told E! News. “Yes, Wilmer was a gentleman and picked up the tab to pay for their food.”

Lovato and Valderrama ended their longtime relationship just three months ago and while Lovato has been rumored to be dating UFC fighter Luke Rockhold — the singer apparently had a few words of advice following Valderrama’s dating news.

“You have to be capable of being honest with yourself before you can get honest with other people,” Lovato tweeted.

While fans speculated if Lovato’s tweet was a subtle dig at her ex-boyfriend, Valderrama and Kelly were seen lounging together in Cabo on Saturday, enjoying another Mexican vacation.
