It was announced several weeks ago that actor Will Ferrell will guest star on the final four episodes of season seven of The Office.

Rumors have been circulating the Internet on whether the famous comedian will replace Steve Carell at Dunder Mifflin full-time.

Steve Carell, who plays the branch manager Michael Scott, is leaving the show after seven seasons.

I just think it's time ... I want to fulfill my contract. When I first signed on I had a contract for seven seasons, and this coming year is my seventh. I just thought it was time for my character to go, Carell said of his departure from the show.

Ferrell will play Deangelo Vickers, a branch manager that comes in as Carell's Michael Scott begins leaving, in the final four episodes, and possibly onto next season.

[Deangelo Vickers] loves the American Southwest, and he's just kind of in his own way going to step into Michael Scott's shoes and try to fill them, Ferrell said of his character.

I'm friends with Steve and a fan of the show, and I just selfishly wanted to do one episode with him, and they pitched multiple ones, and I said, 'That'd be great.'

We are proud to continue The Office's tradition of discovering famous talent, and we hope that once America gets a good look at Will, they'll see what we see, tremendous raw sexuality, said Paul Lieberstein, the show's actor who plays Toby.

While there is much speculation regarding Ferrell's involvement with the hit NBC show, nothing is official yet.

The show is great, and the ensemble is so strong, and the writers are great, so it's just one part of the ensemble drifting off. They've incorporated so many new characters and so many new, great storylines that I have no doubt it'll continue as strong if not stronger than ever, Carell said.

Ferrell's character will appear in the April 14 episode. Carell's last episode will air on April 28. Carell's Michael Scott has already set up his departure by proposing to his girlfriend/co-worker Holly and announcing that they will be moving to Colorado.
