The 1D star showed his support for Nicole Scherzinger's act by attending a secret gig in London last night.
And it seems that his girlfriend Eleanor Calder is also an Adam fan - after she turned up to the exclusive X Factor event at Cornerhouse in super cool Shoreditch.

Adam, who looked cute in black jeans, a white tee and faded denim jacket - with an Aiden Grimshaw-style beanie on his head - emerged from the venue with a big grin on his face.
And we can hardly blame him for being a happy chappy, what with the support of a One Direction (and all the Directioners) behind him!
Louis has been a big fan since he first saw Adam on The X Factor stage back last month and tweeted: "James Arthur and Lucy Spraggan smashed bootcamp !! Also that Adam guy with the hat I would buy his record love his voice !"
And when Nicole failed to pick Adam for her Final 12, the popstar tweeted his outrage, posting: "What the f*** is going on !?!?!?!? Adam was sick !!!!!"
And once the Wildcard twist had been revealed Louis made sure his fans knew who he'd be voting for, tweeting: "Guys let's get behind @Adam_Burridge ! Please vote 09020505117"
Meanwhile this morning Adam posted a picture of the One Direction singer holding up his voting number. Naw! It's a proper bromance.
He tweeted: "Little pic of my main man @Louis_Tomlinson cheers for the support bro!! RT"
