Adele has been approached to play a villain in 'The Secret Service'.

The 25-year-old singer - who was previously involved in the award-winning blockbuster 'Skyfall' - has reportedly landed a cameo role of a baddie in Matthew Vaughn's new spy film and will join the likes of David Beckham and Sir Elton John in an already star-studded cast.

A source told The Sun newspaper: ''Adele is exactly what Matthew is looking for.

''He wants the highest-profile names in various fields to boost the film's cause and turn it into a mega-money franchise.

''You can't get much bigger than Adele in music, which is why he's so keen to get her involved. She'll be great value on the big screen.''

A spokesman for Adele has refused to comment on the news.

The film - which is based on a spy graphic novel by Mark Millar and Dave Gibbons - stars Colin Firth and Sir Michael Caine as superagents fighting a team of villains headed by Samuel L. Jackson and will feature cameo appearances from a range of A-list stars.

Vaughn - who previously directed another Millar comic book adaptation, 'Kick-Ass', as well as 'X-Men: First Class' - has been eyeing a big Hollywood name for the role, and previously offered the part to Tom Cruise and Leonardo Dicaprio.
