Entertainment Weekly reports that the former WWE star will star as Greta, a recurring character played by a different actor each week. Keibler will follow Olivia Munn and Isaiah Mustafa in the role.
“Greta can be a guy or a girl, which is brilliant,” said series star Zachary Levi. “The Buy More has now been taken over by the CIA and it’s a fully-functioning operation by the government, so there are these constant agents that are in the store. First it was Olivia Munn... and [next was] Isaiah, who was a hoot to work with.”
Keibler recently made guest appearances in Psych and How I Met Your Mother.
The third episode of the season - which will also feature Nicole Richie and 'Stone Cold' Steve Austin - is due to air in October on NBC.
