Demi Lovato recently showed some PDA with ex-boyfriend Wilmer Valderrama.

The "Tell Me You Love Me" singer started fueling reconciliation rumors with her former beau after they were spotted on a lunch date on Saturday. The duo sported matching hoodies and dined at Sol Y Luna restaurant in Los Angeles together. The "That '70s Show" alum and Lovato were all smiles as they ate some guacamole and chips.

An insider told Us Weekly that the exes are frequent patrons of the Mexican restaurant, adding Valderrama is "very nice" every time they visit while Lovato is "always smiling."

"Sometimes they kiss or hug. He usually orders for her," the source continued. "They definitely look like they are boyfriend and girlfriend. They are always laughing and having a good time."

Lovato, 25, and Valderrama, 38, did not kiss during their latest outing. They did, however, left the establishment "with their arms around each other," according to the source.

The "Camp Rock" star and The "NCIS" actor dated for six years until their split in 2016. In Lovato's "Simply Complicated" documentary released in October, she explained why she made a lasting connection with her former boyfriend despite their breakup.

 "I think my heart's always with Wilmer. I think it was with Wilmer, it is with Wilmer, and I think it will be with Wilmer, because you don't share six years with somebody and not give them a piece of your heart," she explained, noting they did not call it quits because the romance just faded.

She continued, "It had nothing to do with falling out of love — we decided together that we're just probably better as friends."

It may take a while before Lovato and Valderrama visit their favorite restaurant, as she has just kicked off her 46-date Tell Me You Love Me World Tour on Monday.
