Chances are, Catherine Tate isn't a household name in your home ... yet.

However, reports indicate the English actress is the frontrunner to join NBC's 'The Office' as the new boss.

Tate will make her 'Office' debut on tonight's one-hour season finale (Thurs., May 19, 9PM ET). She's one of many famous faces -- including Ray Romano, Warren Buffett, Jim Carrey, Will Arnett, Ricky Gervais and James Spader -- vying for the job vacated by Steve Carell's Michael Scott.

Yep, that's a lot of big names, so why is Tate right for the job? Simple: She's pretty damn funny.

The star of her own series, 'The Catherine Tate Show,' Tate has won several BAFTAs and was nominated for an International Emmy.

Since Steve Carell announced his departure from 'The Office' the race has been on to find a replacement for his character, Michael Scott, as the manager of the Scranton branch of Dunder-Mifflin.

Speculation's rife about who will step up to the plate, and just about every guest star in the current season has been linked with the top job. Most recently, we reported that 'Office' creator Ricky Gervais could be taking over from Carell, but now even more names have been added to the ever-expanding list of nominees.

The upcoming Season 7 finale was already set to be a star-studded affair, with Gervais, Will Arnett and Will Ferrell all having booked guest slots. However, according to TVLine.com, yet another comedic trio has signed on for the episode -- Ray Romano, James Spader and Catherine Tate -- and now they're all being linked with the top job.

Is there a grain of truth in the rumors, or is it all just smoke and mirrors?
