British boy band One Direction will continue on its quest to take over the United States when the band makes its inaugural appearance on one of the country's biggest late night talk shows.

One Direction - made up of band members Niall Horan, Zayn Malik, Liam Payne, Harry Styles and Louis Tomlinson - will make their first appearance on "The Late Show" with David Letterman.

"The Late Show" officially announced One Direction's guest spot with a post on its official Facebook page on Thursday.

"JUST ANNOUNCED: One Direction to make their first appearance with Dave on Friday, December 7," the post read.

The band has been garnering more and more success in America as its hit songs light up the charts and as the personal lives of the group's members make their way into tabloids across the country.

One Direction band member Harry Styles has grabbed the attention of gossip magazines for his budding relationship with country music superstar Taylor Swift. Swift was spotted flirting and holding hands with Styles when she visited the set of "The X Factor" to appear on the singing competition show and perform a song and Styles tagged along.

Co-host Mario Lopez, who shares his duties with co-host Khloe Kardashian, gave the audience the scoop about Swift and Styles' time together, which he witnessed first hand during rehearsals for the "X Factor" live taping.

"Taylor Swift was the special guest performer, and [here's] a little inside scoop for you," Lopez said. "During rehearsals, Harry from One Direction came and slapped me on the back, and said, 'Hey, Mario, how ya doing?' And I said, 'What are you doing here?' And he sort of [pointed] toward Taylor."

Lopez went on to give a little more gossip about the couple, adding that the pair "walked off hand in hand" when Lopez saw them together.

"So Taylor Swift and Harry from One Direction — you heard it here first. [They're] officially hanging out, I can say that much," Lopez said.
