Ariana Grande and Ricky Alvarez’s romance heats up as he supports singer at NYC concert

He kept a low profile in a blue flannel and black hat.

Social media users gushed over the show of support in the comments section, with many also raving over Alvarez’s moves.

“I be forgetting that he was her BACKUP DANCER. he has rhythm,” one fan wrote, while many praised him for seemingly recording some of his partner’s performance.

Alvarez’s surprise concert appearance came two days after he and Grande, 33, engaged in Central Park PDA.

The pair cozied up on Thursday, putting their arms around each other on a stroll.

The Grammy winner initially dated Alvarez between 2015 and 2016 — going on to get engaged to Pete Davidson, marry Dalton Gomez and date Ethan Slater.

Page Six confirmed last week that Grande and her ex have “rekindled things” but aren’t “rushing back into the relationship.”

Instead, we hear they are “enjoying spending time together again and seeing where things go without putting too much pressure on the relationship.”

A source told us, “She has a lot on her plate at the moment and is still incredibly busy with her tour schedule, so they’re taking things one step at a time.

“Ricky has remained close with Ariana’s family over the years,” the insider added. “That’s something she really appreciates. He has also made an effort to show up and support her while she’s on tour, which hasn’t gone unnoticed.”

Alvarez, notably, made headlines for his presence at a Texas show in June, which coincided with Grande changing “Thank U, Next” lyrics about him.

Instead of saying their relationship makes her “laugh,” the “Victorious” alum sang that he has “still got [her] back.”

They were subsequently spotted out and about on the Fourth of July.

News broke last month that Grande and Slater, 34, are over — and the Broadway star reportedly found out through mutual friends that his “Wicked” co-star is back with Alvarez.
