He is the bassist and youngest member of the pop rock band Mc Fly. In 2003, a then 15 year-old Poynter auditioned for and subsequently became the bass player for the English band Mc Fly.
The band consists of Poynter, Tom Fletcher (vocals/guitar), Danny Jones (guitar/vocals), and Harry Judd (drums).
Off the catwalk, Poynter is a front-row fixture at LCM and other global fashion weeks, garnering invites from top brands including Topman, Burberry, Louis Vuitton, Moschino, and Saint Laurent Paris.
Poynter is credited as a lead writer and cowriter on many of Mc Fly's tracks.
He served as the lead writer for Mc Fly's seventh number-one hit single 2007's "Transylvania." He also wrote an unrecorded track called "Silence Is a Scary Sound." and One Direction (for the track "I Would" from the album Take Me Home and for the track "Don’t Forget Where You Belong" from the album Midnight Memories, respectively).
Also in 2012, the band debuted their first written autobiography, Mc Fly: Unsaid Things... The Anthology tour, in which they will play all five of their albums, will serve as Mc Fly's first live reunion since 2013.
The tour was postponed from June until September 2016 after drummer Harry Judd injured his neck.
Mc Fly star Dougie Poynter was dumped by Saturdays star Frankie Sandford - who is now dating footballer Wayne Bridge - in November, and it was a decision that left him shell-shocked.
