Louis Tomlinson is ''excited'' about becoming a father.

The One Direction star confirmed he is expecting a baby after a brief relationship with stylist Briana Jungwirth during an appearance on 'Good Morning America'.

When asked about the news by host Michael Strahan, the 23-year-old singer said: ''Obviously it's a really exciting time, so I'm buzzing, thank you.''

Meanwhile, fellow 'Night Changes' hitmaker Liam Payne previously admitted he was ''shocked'' when he found out Louis was going to be a father.

He said: ''Well obviously I was a bit shocked but he's taken super well to it. And he's very excited with what's going on with him at the moment and I feel that stuff like that happens sometimes ... He's taking it very seriously.''

Of Briana, Liam added: ''Yeah she's really nice, she's a lovely girl.''

Meanwhile, a source previously claimed that Louis has ''real feelings'' for Briana.

They said: ''There are very real feelings there. It's not just about the baby.

''Louis is sacrificing all his spare time to see her. They spent last Sunday together after he made a whirlwind stop in LA during what was a rare day off for the band. And they spent the entire Fourth of July weekend together meeting each other's families.''
