Ellen's "Irish brother from another mother" made his US solo debut on 'The Ellen Show' this week and it went down a storm.

Mullingar's finest (sorry Bressie) Niall Horan is turning into quite the charmer as he spreads those wings and flies solo for the first time, bonding with DeGeneres and making the audience swoon as he visited her show, taking in a game of 'Who'd You Rather?' while he was there.

We won't spoil who he ends up 'Rather-ing' but let's just say it's a tad awkward because that is some very familiar territory.

Horan also performed his single 'This Town' for Ellen and he had the audience in the palm of his hand.
