AceShowbiz - Ellie Kemper reunited with her "The Office" co-stars Jenna Fischer and Angela Kinsey as she guest hosted Monday's (December 23) instalment of "The Ellen DeGeneres Show".

For her third appearance as a stand-in presenter on the popular show, Ellie, who played Erin Hannon on the series from 2009-2013, welcomed her pals onto the set for a sit-down chat, as they discussed the hit sitcom's longevity.

"It's over, but it's getting a new popularity among younger people," the "Unbreakable Kimmy Schmidt" star suggested, as Jenna noted she's "had young fans come up to me in stores and say, 'You look like an older version of that girl Pam from the office'."

The trio also discussed the possibility of a reboot of the hit NBC series and, while all of the ladies agreed they would be interested in reuniting for some sort of project, they didn't all seem too keen on a full blown revival series.

"I would not do an Office reboot but I would love to do a reunion special: I would like to get us all together again," Jenna said, whereas Angela chimed: "I would do anything they would call me to do - so if you want to call me, I'm around."

Ellie also seemed on board, adding: "I'm with you, Angela - if you call me, I'm around ... I will be there - Angela and I are rebooting The Office!"

"The Office" aired for nine seasons from 2005 to 2013.
