Why Is Niall Horan Wearing Miley Cyrus' Pants?

Cannot. Handle.

Well that's a new look for Niall. Just hours before One Direction took the stage in New Jersey's MetLife Stadium, Niall Horan found himself in a pair of Miley Cyrus' pants.

The blue-eyed pop star took to Twitter with a (mostly) shocking photo of himself in a pair of uber-tight Miley-covered pants, throwing out his tongue in homage to the "Adore You" singer.

"@MileyCyrus you left these in New Jersey! They are comfortable, not gona lie #twerk #tongueout"

Miley was honored by the display of tongue-flailing affection, tweeting back, "@NiallOfficial f--kkkk yassss."

Apparently, the pants are part of the merch that Miley is selling on her tour. How did Niall get his hands on a pair? He probably has his ways...

Tonight marks the third North American stop in One Direction and 5 Seconds of Summer's Where We Are Tour, which opened in Toronto, Canada over the weekend. Cyrus, coincidentally, is also on the third stop of the North American leg of her Bangerz tour, which kicked off on Long Island, NY and is making its way into Pittsburgh tonight (August 4).

We'll cross our fingers that the musciains continue to cross paths as they tour the country through the end of this fall.
