Tom Fletcher and wife Giovanna have named their son Buzz Michaelangelo.

The McBusted singer and his spouse welcomed their first child into the world last night (13.03.14) and announced his unusual moniker this afternoon.

Tom tweeted: ''For those asking, our son's name is Buzz Michelangelo Fletcher.

''And he's on his 3rd nappy. Full of poop, that's my boy!''

He later insisted the unconventional name wasn't a joke.

He added: ''...and yes I'm being completely serious, my son is called Buzz :D(sic)''

Earlier this week, Giovanna - who married the 'Star Girl' hitmaker in 2012 - admitted she and Tom, who didn't know the sex of their baby before he was born, had chosen ''unusual'' names for a son.

She said: ''We have two girls' names and three boys' names picked. The boys' names are quite unusual and the girls' names are pretty.''

The 29-year-old writer gave birth two weeks early, but had admitted she had been preparing for labour for a while.

In an interview with this week's OK! magazine, she said: ''I've started drinking raspberry leaf tea to bring the labour on - but I'm going to try and remain chilled until it all happens.''
