David Brent is to return for a one-off special to air on Red Nose Day.
The Office Revisited will show viewers what Ricky Gervais' character has been up to in the decade since leaving his job as a middle manager at a paper company in Slough.
Brent's Back http://t.co/w8W2zUT3Gm See the the whole sketch as part of Comic Relief on Friday 15th March.
Gervais told The Mirror: "It has been 10 years since we last saw David Brent.
"I thought it was time to revisit my most famous comedy creation to find out what he's been up to for the last decade and most importantly what he's up to now."
In the trailer (above), Brent says he's been "repping, mainly," which helps to fund a music career.
"He is passing on his wisdom to younger would-be rock stars now and is living vicariously through a young performer, Dom Johnson," Gervais added.
"Well, really he is trying to worm his way back into rock and roll.
"Fans of The Office will be excited to know we finally get to hear the whole of 'The Serpent Who Guards the Gates of Hell' and an amazing Brent self-funded video, 'Equality Street.' Horrendous."
