Louis Tomlinson's estranged father wants to reconnect.
Troy Austin lost touch with the One Direction star when he broke up with his mother Johanna when Louis was two.
Now, he wants to get back into his life and has denied it is anything to do with his son's new-found fame.
He told the Sunday Mirror newspaper: "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. I'm his dad. We're flesh and blood and nothing can change that. I'm so proud of him I could burst."
The 44-year-old construction worker also claimed Louis' half-sister Georgia is "his biggest fan" and would love the chance to meet her idol.
He added: "It's up to him. I want him to know I think he's fantastic - and that Georgia is his biggest fan ...
She's a teenage girl and her brother is in her favourite band.
"Of course she wants to tell the world and wants to be a part of his life ... She idolises him. All she wants is to be a proper sister to him."
He took 14-year-old Georgia to see Louis, 21, and his Little Things band mates at a recent Nottingham show, but weren't able to reconnect.
Troy revealed: "It was a shame we couldn't see Louis and tell him how brilliant he was. But I know he and the lads are really busy.
"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."
