"Extra" has your first glimpse of Britney Spears in character on the set of "How I Met Your Mother!"
Spears plays Abbey, a nerdy receptionist with a major crush on a dermatologist -- played by Josh Radnor.
The cast praised Britney's performance when "Extra" spoke to them at a cast party last week. "She seemed very nice and even-keeled," said Neil Patrick Harris. Added Alyson Hannigan, "She's great and she's funny and I think she's going to remind people how talented she is."
Britney's appearance on "How I Met Your Mother" is set to air March 24 on CBS.
