Unfortunately for host James Corden, who walks in after Styles and doesn't have his identification on him, the same maneuver doesn't quite pan out with the same effect.
Styles proved he was up to the task on Monday night by opening the show with a sketch in which he arrived at the TV studios for filming and was confronted by a strict security guard who refused to believe he was a pop superstar.
We at heat, like every other rational member of the human race, are very much in love with Harry Styles. Doing stuff like this, it would be hard not to get nervous.
Aaron revealed that he and his wife have a small farm and they have a coop of chickens, which they have named after all of the Kardashians.

The joke came just days after Jenner and Styles' names were once again thrown together after Hollywood Life claimed that Kendall' mum Kris Jenner admitted she wished the twosome's romance had worked out.
At mention of Kendall, Styles, 23, reached for his mug, kept his head down and later clapped. Especially when Aaron said they "lay every day" and James Corden asked "do they lay every day, Harry?".
And of course, Styles performed his poignant, Bowie-esque hit "Sign of the Times".
With his debut solo album Harry set for a No. 1 bow atop the USA and United Kingdom charts, Styles naturally performed a song from it, "Carolina". "I don't really talk about it I guess", Styles says. The track appears on the former One Directioner's self-titled debut album.
