The intimate pic was posted a day after the couple were spotted sharing a smooch at Monday's New York Knicks game at Madison Square Garden. "Jumbotron vibes with my boo," Chmerkovskiy captioned a video of the moment.
"Why is he so cute tho," Rose gushed over her boyfriend in an Instagram post from the game.
"They were really cute," an onlooker told ET of the couple's courtside date. "They look like they have a lot of fun together!”
The two played coy about their relationship at first. When speaking to ET in October, Chmerkovskiy responded to fans saying he looked cute with Rose, boasting, "I'd make a cute couple with a lot of people, you know what I'm sayin'?"
