Mark Cavendish and wife Peta Todd announce they've welcomed their third child together

Mark Cavendish and his wife Peta Todd have announced the arrival of the newest addition to their family.

Mark, 33, announced the happy news via Instagram last night when he shared a snap of the newborn, also revealing his cute baby name.

Alongside the adorable picture, he wrote: ‘Welcome to the world, Casper Cavendish. Seeing your beautiful little face has given me once again the joy of loving more than I ever knew possible. Your Mummy @petatoddlar was incredible once again. I’m the proudest Daddy in the world. I love you so much 💙’

Peta, 31, also shared a couple of images with her 30,000 followers. The first one showed her cradling her son, just moments after he was born, and the second showed Casper swaddled in a white blanket as he slept peacefully.

Peta captioned the pictures: ‘So on Tuesday our little family welcomed our newest member... Casper Charles Cavendish, weighing 6lb10.5 ... we are all completely in love. It feels like he was here all along. Thank you to the amazing medical team that cared for us & to @markcavendish for being everything I needed. 💙 #welcometotheworld #newborn#motherof4 #love.’

Mark and former glamour model Peta already have two children together, a six-year-old daughter named Delilah and a two-year-old son named Frey.

Peta also has a son named Finnbar from a previous relationship, who was born in 2006.

She first met cyclist Mark in 2010 and the pair married on October 5, 2013 in London.

Speaking in a recent interview, Mark said that when he’s not racing bikes, he will always be found spending time with his family.

‘When I’m with my kids I want to be dad, and when I’m with my wife I want to be husband,’ he said. ‘I like to go on cinema dates with my daughter, see the My Little Pony movie or something, y’know. I can’t remember any of the names – is it Applejack or something like that?

‘And I like to play FIFA with my oldest boy. I play as Real Madrid normally – I’m not the best. I love my driving sims too, Grand Turismo, Project Cars. But I always drive a McLaren.’
