Tom Fletcher has become a dad for the first time.

The McFly singer's wife Giovanna gave birth to a ''beautiful baby boy'' on Thursday night (13.03.14) and the happy couple - who first met when they were 13 and tied the knot in May 2012 - are thrilled with their new arrival.

The 'Star Girl' singer announced on Twitter this morning: ''Yep, Mrs Fletcher gave birth to our insanely gorgeous son yesterday at 7pm. He is healthy, beautiful and I've already changed his nappy.''

Tom's joke comes after he admitted he was studying videos of how to change nappies ahead of his child's arrival because he was determined to be a hands-on dad.

Meanwhile, Giovanna couldn't contain her excitement as she updated her followers about the baby's birth.

She enthused: ''THRILLED to announce the safe arrival of our little BOY! Born last night at 7pm! I can't stop staring at and kissing him! I'm in love!''

The childhood sweethearts publicly announced the pregnancy in a YouTube video last October and admitted they had chosen not to find out the sex of the baby.

Tom said: ''We don't know the sex of the baby. We're taking bets from all our friends on whether it's a boy or girl, what date and all that malarky.''
