Steve Carell In 'The Office' Finale: Cameo Appearance Planned (REPORT)

When The Huffington Post reached out to NBC, the network declined to comment. TVLine reports Carell's appearance is more of a cameo than a guest spot.

After it was reported that Carell was on set when "The Office" finale was filmed, he made a surprise appearance at "The Office" wrap party in Scranton, PA on Saturday, May 4, further fueling speculation.

NBC released a brief description of the finale that reveals the Dunder Mifflin crew will gather for a reunion and a wedding. Could viewers see Carell's Michael Scott at the altar with Amy Ryan's Holly?
