Keep in mind, they are some definitely tight pants, but Nialler was up for the challenge of stuffing himself in the leggings, throwing out his tongue and showing off his new look to the world, with a shoutout to Miley herself.
He tweeted the pic, writing: "@MileyCyrus you left these in New Jersey! They are comfortable , not gona lie #twerk #tongueout"
Miley was on board with Nialler's fashion choice, tweeting: @NiallOfficial f*kkkk yassss."
Meanwhile, Niall's dating life is making headlines again, as British actress Brooke Vincent shot down rumors, telling The Sun recently: "Niall has been my friend since he started on the X Factor but because I'm single and he said he fancies me it's assumed we'll get together."
Maybe she'd change her mind if she saw him in these Miley pants?
