Matt Baker first broke onto our screens as a young Blue Peter presenter in 1999, where he stayed for 7½ years.
The nature lover then presented a series of animal shows and is now the face of BBC One's Countryfile, regularly pulling in 6 million viewers on Sunday evenings.
Matt joined Blue Peter midway through his university degree. During his time on the show he trained as a stuntman, slept in jungles and lived with a nomadic family in the Atlas Mountains in Morocco.
He won two BAFTAs for Best Children's Presenter and an RTS Award. He left the show in the summer of 2006 and presented daytime shows such as BBC One's City Hospital. He also made the final of BBC Sport Relief's showjumping series Only Fools On Horses.
He joined the BBC's sports team as a presenter and commentator for gymnastics events, ranging from the Glasgow Grand Prix Gymnastics and Women's European Gymnastics Championships right through to the 2008 Beijing Olympics.
He loves countryside and animals and has presented Animal Rescue Squad, One Man And His Dog, Summer Countryfile Diaries, Crufts and Animal Rescue Live.
Matt has hosted four Family Proms in Hyde Park and many live Proms from the Royal Albert Hall. He was also the co-host of the Olympic Handover Concert, officially marking the start of London's tenure as Olympic host city.
In 2009, Matt was one of the celebrities who took part in Around The World in 80 Days for BBC Children in Need, travelling from Kazakhstan to Mongolia with his Countryfile co-host Julia Bradbury.
Matt was born in County Durham, where he grew up in the dales on his family's sheep farm. He has one sister and two step-sisters. As a boy, he was a British Gymnastics champion.
In the late 1990s he worked as a DJ and toured with disco-dancing groups. He played the part of 'Butch Vendor, the LA Bartender' in a comedy disco show, Disco Inferno. He had to juggle wooden clubs that were painted to look like spirits bottles, and do back flips.
Matt lives in Hertfordshire with his wife and their two children, Luke and Molly.
Whilst on Blue Peter, Matt broke the world record for the highest altitude towed hang-gliding launch.
