Lily-Rose Depp and 070 Shake's romance is heating up.

Case in point: Their recent PDA-packed outing. On June 11, the Idol star and the rapper couldn't keep their hands off each other during a lunch date in New York City.

After dining at Lure FishBar, Lily-Rose wrapped her arm around 070 Shake—born Danielle Balbuena—as they visited several local boutiques, including trendy antiques store The Vintage Twin. At one point in the day, the couple shared a passionate kiss on the sidewalk, with 070 Shake's hand seen sliding down the back Lily-Rose's black miniskirt during the steamy moment.

For the outing, Lily-Rose paired her skirt with a black zip-up hoodie, wedged sandals, thin sunglasses and a burgundy handbag. Meanwhile, 070 Shake coordinated with the actress in a loose black tee over a long-sleeved short, patterned pants and chunky platform boots.

The sighting comes a month after Lily-Rose confirmed her romance with the New Jersey native. Sharing a photo of the two kissing, the daughter of Johnny Depp and Vanessa Paradis wrote in a May 11 Instagram Stories, "4 MONTHS WITH MY CRUSH."

Since then, Lily-Rose, 24, and 070 Shake, 25, haven't been shy with their PDA. On May 25, the actress was seen greeting the musician with kisses after returning to the Los Angeles International Airport from her trip to France for the Cannes Film Festival.

And while Lily-Rose is notoriously private about her personal life, she has previously shared her general outlook on sexuality.

"You don't have to label yourself, because it's not set in stone," she explained to Nylon in 2016. "It's so fluid and there's so much pressure on kids to label themselves and say, 'This is what I am, this is what I like.'"

She added at the time, "It's not anybody's business, because I am going to date whoever I'm going to date."
