Early career Griffin began his radio career in 2000, aged 16 on
pirate radio station Freek FM, specialising in garage and jungle. Here he was known as DJ Devstar and presented with Yates (who used the moniker MC Nobizzi). In 2002, whilst studying for his A Levels at
The Ravenscroft School, Griffin landed a job co-presenting the children's interactive TV show
Smile (credited as DJ Devstar) alongside Yates,
Fearne Cotton and
Nev the Bear. Six months into filming, he was approached by
BBC Radio 1Xtra to present a Saturday afternoon show with Yates. In 2003, Griffin left
Smile to concentrate on his radio career.
Acting In 2006, Griffin created and starred in children's sitcom
The Crust. He has starred as himself in
Friday Download: The Movie, as a result of campaigning at length on air to get himself a role in a
B movie.
DJ Griffin was a member of the Rebellious music collective and played in venues at
Ayia Napa and
Faliraki. In September, he moved from the weekend slot to replace
Greg James as host of the weekday early breakfast show, between 4am and 6:30am. In March 2014, he left the weekday slot and returned to the weekend breakfast show, taking over from
Gemma Cairney. He regularly presented
The Radio 1 Breakfast Show (sitting in for
Nick Grimshaw), the
Scott Mills show and the
Greg James show as a relief presenter. In 2018, he and
Alice Levine began hosting their own show,
Dev & Alice, in the weekend breakfast slot. The duo were moved to the weekend afternoon show the same year. On 9 August 2020 the final show aired, following the announcement of Levine's departure from Radio 1. In November 2020,
BBC Radio 1 announced major scheduling changes for the end of 2020 and 2021. Griffin, along with
Huw Stephens and
Phil Taggart would not be rejoining the lineup in 2021. The latter two are not leaving the
BBC all together, and are instead returning to their former shows on
BBC Radio Cymru,
BBC Radio 6 Music and
BBC Radio Ulster respectively. Instead, Dev departed the BBC, and joined
Heart after 18 years with the corporation. His last show was 13:00 – 16:00 on 20 December 2020. He made his Heart debut on Saturday 2 January 2021, when he launched his brand new show 12:00-16:00. As of January 2022, Dev presents Heart's Evening Show from 7-10pm Monday to Thursday, replacing Mark Wright, who has moved back to weekends.
Television In 2016, Griffin and Alice Levine competed in a BBC Bargain Hunt Children in Need special. They took on Radio 4's Nick Robinson and Aasmah Mir. Griffin reached the final of the 2017 series of
Celebrity Masterchef, alongside
Ulrika Jonsson and eventual winner,
Angellica Bell. Griffin participated in
the 17th series of Strictly Come Dancing, partnered with professional dancer
Dianne Buswell. They became the third
Strictly couple to leave the show after losing a dance-off to
Emma Weymouth and
Aljaž Skorjanec. His elimination caused controversy and complaints from the viewers as his voting lines weren't even open in that week's public vote which meant that the elimination was 'fixed'. In April 2019, Griffin took part in the first series of
Celebrity SAS: Who Dares Wins. In October 2020, Dev participated in a celebrity edition of
The Chase. In July 2023 Griffin was the subject of an episode of
Who Do You Think You Are?, where he discovered that a maternal great-uncle had participated in the
Easter Rising at Dublin City Hall. ==Radio presenting==
