Niall Horan shares photo in Miley Cyrus' pants

 One Direction's Niell Horan has officially come out as a "smiler."

The 20-year-old Irish pop star took to Twitter Monday to share a photo of himself in a pair of tight Miley Cyrus-printed pants.
"@MileyCyrus you left these in New Jersey! They are comfortable, not gona lie #twerk #tongueout," he tweeted at the singer.

Horan accessorized the look with a backwards baseball cap, a white tee and white socks. The singer appears squatting and sticking his tongue out a la Cyrus for the pic.
The "Wrecking Ball" singer responded to Horan's post with a simple: "[expletive] yasssss."
MTV reports the pants are part of Cyrus' Bangerz tour merchandise. There is no word, however, on how Horan got ahold of them.
Horan's band, One Direction, was in New Jersey Monday for the third stop of the Where We Are tour alongside 5 Seconds of Summer at the MetLife Stadium. Cyrus is currently on the North American leg of her Bangerz tour.
