One Direction On The X Factor Australia - Harry Styles Falls In Love!

11 September 2012

X Factor Australia ramped it up a notch last night, the mentors were decided, and some seriously big stars got involved!

Ronan Keating got to mentor the supergroups, Nat Bass got the under 25 girls, Mel B got the under 25 guys and Guy Sebastian got the over 25 year olds!

Find out why Angel Tupai made the judges cry!

There was a bit of controversy on Twitter after Guy Sebastian was allocated to mentor his good friend Sammi in the over 25 year olds group, but we don't think it matters. Guy will give everyone a fair shot!

The biggest excitement of the night came when One Direction guest starred in the home visits section of the show, meeting all the supergroups and getting to watch them perform!

Harry Styles was the most excited by the performance of the newly named 'Black Ivory' all female group, and even admitted 'I think I'm in love with them... I'm not even kidding.'

He even singled out the gorgeous Briden Starr as being someone he's got his eye on! She has since copped a lot of criticism on Twitter!

Louis turned around to Zayn at one point to slap him on the knee, and Niall couldn't wipe the grin off his face.

Tonight we see Usher, Alicia Keys and Kesha come on board... but until then, re-live the priceless moments of One Direction on X Factor below -- Too funny!
