Those Ariana Grande and Mikey Foster dating rumors are heating up!

According to Us Weekly, the rumored couple was spotted holding hands during a night out in Chicago on Monday (August 5). Eyewitnesses saw them at Siena Tavern with a group of friends and Grande's mom, Joan. “Ariana and Mikey were holding hands at one point while they were there,” a source told the outlet.

This is actually the second time they're seen at Chicago's Siera Tavern together. The 26-year-old pop star and Social House singer reportedly sat “next to each other during dinner” at a surprise party for one of Grande's bodyguards on Sunday (August 4) following her headlining performance at Lollapalooza.

Neither Grande or Foster has confirmed their relationship status, but they first sparked dating rumors earlier this month when they dropped their collaborative "Boyfriend" music video. In it, not only do the two play love interests with great chemistry, but they later engage in a steamy bathroom make-out session.

Naturally, fans began to wonder if the pair were together IRL. Some even pointed out that Foster posted a very heartfelt —and boyfriend-like — tribute for Grande on her birthday in June.

“Ur one of the most incredible people the universe has to offer. I hope this year offers u nothing but the joy u deserve. Love u. Happy birthday," he wrote on Instagram alongside a picture of baby Grande.
