Miley Cyrus and Pete Davidson are hanging out.

The two stars appeared together on the "Tonight Show Starring Jimmy Fallon" Thursday night where they cut up with the actor and comedian about Davidson’s eyebrow-raising romance with Kim Kardashian all while promoting a New Year’s Eve special they’re co-hosting later this month.

However, it wasn’t until the two left the studio that things got interesting, according to a sleuthing source who relayed to Page Six that the "Wrecking Ball" singer, 29, was spotted entering the underground garage of the 28-year-old "Saturday Night Live" star’s Staten Island condominium.

"They left NBC around 8:30 and arrived at Pete’s place around 9:40 p.m.," the insider told the outlet, noting that both of the star’s SUVs were obscured as they each entered the building.

"It should have been me," she sang, adding, "on the week of promoting our special."

"Now you’re standing there saying ‘I do’ / Holding hands with somebody new / It should have been me," Cyrus quipped to the "Suicide Squad" actor. They also revealed that they had previously gotten matching tattoos after filming an "SNL" sketch together.
