Jessie J isn't the only one whose barnet is undergoing a radical transformation for Comic Relief.
Nick Grimshaw has done his bit for the charity by dying his hair pink and blonde.
The Radio 1 Breakfast Show host stuck to his promise to go through with the makeover after his show raised £250,000 on Thursday.
Debuting his new look on Twitter, he paid homage to Nicki Minaj, who has previously sported a similar 'do in the past, by nicknaming himself Nick Grimaj.
Nick is also due to host a section of Friday's Comic Relief telethon, which also sees the return of 'The Vicar Of Dibley' and 'The Office''.
