One Direction heartthrob Louis Tomlinson expressed his anger on Twitter in response to his estranged father's public attempts at reconciliation.

The 21-year-old singer's biological father, Troy Austin, gave an interview with Sunday Mirror yesterday, detailing his strained history with Tomlinson and revealing he wants to be part of the star's life again.

"I'd like to start off the day by saying a big fuck you to 'the mirror' :) on a happier note huge love to all out fans, you keep us going!!" Tomlinson tweeted.

Austin, a 44-year-old construction worker, split from Tomlinson's mother Johannah Poulston when the singer was 2 years old. He recently took his daughter, Tomlinson's half-sister Georgia, to the Nottingham leg of the band's tour.

"Seeing Louis on that stage was amazing. He's in the ­biggest band in the world and I'm the proudest dad in the world. I just hope he knows it," he told the Sunday Mirror.

Though Austin and Georgia tried to meet Tomlinson at the Nottingham concert, they were reportedly told the band had to "rush off".

"It was a shame we couldn't see Louis and tell him how brilliant he was. But I know he and the rest of the lads are really busy. Georgia was gutted - she's his half-sister after all," Austin added.

"I haven't been there for most of his life, so I understand I'm not one of his main priorities. He knows we were in the crowd and now I want to tell him what it meant to me to see him up there. I cried buckets. I thought the best concerts I'd ever been to were U2 and The ­Waterboys, but not any more," he said.

Austin last saw Tomlinson two years ago when the star got in touch to tell him he was appearing on the reality show The X Factor.

"Seeing what he's done with his life makes me so happy. I know people will think I'm only ­interested in being part of his life again because he's rich and famous. But it's not about that," he continued.

"I'm his dad. We're flesh and blood and ­nothing can change that. I'm so proud of him I could burst. Of course, I would love to see him again and have a proper relationship with him. What dad wouldn't? But it's up to him. I want him to know I think he's ­fantastic - and that Georgia is his ­biggest fan."
