Niall Horan’s brother has revealed he would be happy for the One Direction star to go out with Katy Perry.

Greg Horan told the Irish Sun that he’d give the thumbs-up to any potential romance between the boyband star and the 'California Gurls' singer, who briefly kissed at Thursday’s MTV Video Music Awards and continued to flirt on Twitter after the ceremony:

“I wouldn’t mind if he went out with her at all — I don’t care when people talk about age differences and all that.

“Niall wouldn’t be where he is today without Katy really — she put him through on X Factor and has been a great support to him. I know she’s proud of him and they are good friends.”

Greg also added that Niall’s family are thrilled that One Direction managed to pick up three awards at Thursday night's event:

“My mother and father were both talking to him and I texted him just to say how proud I am.”
