Harry Styles didn't come to "The Late Late Show with James Corden" only as a musical performer, but also as a guest host. On Tuesday, May 16, he surprised the audience when the 23-year-old heartthrob, instead of the regular host, stepped out of the curtain after the band introduced James Corden.

Styles went to deliver the monologue, which included digs at Donald Trump and Hillary Clinton. "Of course, the big story of tonight is that Donald Trump shared secret information with the Russians last week," he said. "The good news for Trump is that he has been named employee of the month by Russia."

The One Direction member then took a light jab at Clinton's newly-launched Political Action Committee called "Onward Together". "Experts are calling it 'bold,' 'ambitious' and six months too late," he said. He also poked fun at the "Pirates of the Caribbean: Dead Men Tell No Tales" hacking scandal.

As a host, Styles introduced all the guests, swapping places with Corden who dressed up as the singer. The ex-boyfriend of Taylor Swift also delivered a segment called "Side Effects May Include".

As for his musical performance in the second night of his week-long residency, the former "The X Factor" contestant sang "Carolina" off his debut solo album "Harry Styles".
