VIDEO: DOWNTON ABBEY Star Allen Leech Talks About Looking Like Niall Horan on THE LATE LATE SHOW

James Corden asks "Downton Abbey" star Allen Leech about the popular observation that he and Niall Horan look alike, a comparison the (slightly) elder Allen doesn't mind at all. And Allen tells James why he's sure he absolutely cannot sing like his doppleganger. Watch the clip below!

Each week night, THE LATE LATE SHOW WITH JAMES CORDEN throws the ultimate late night after party with a mix of celebrity guests, edgy musical acts, games and sketches. Corden differentiates his show by offering viewers a peek behind-the-scenes into the green room, bringing all of his guests out at once and lending his musical and acting talents to various sketches. Additionally, bandleader Reggie Watts and the house band provide original, improvised music throughout the show. Since Corden took the reigns as host in March 2015, he has quickly become known for generating buzzworthy viral videos, such as Carpool Karaoke."
