Britney Spears is glad to be back on TV.

She thinks working on How I Met Your Mother was great.

"Working at How I Met Your Mother has been so terrific," Spears said in a deep, thought-provoking statement.

The singer is scheduled to play Abby, a dorky receptionist, on the March 24 episode of the hit CBS comedy starring Neil Patrick Harris.

"Everyone, including the cast, the crew and the producers, has been wonderful and Abby is such a fun girl to play," Spears said. "I'm having a blast!" Hooray, y'all!

The troubled pop singer, who hopefully didn't spontaneously strip down to no panties on the set, filmed scenes yesterday in L.A.

Her mom, Lynne Spears, was spotted visiting her trailer.

"Britney's not playing a version of herself," How I Met Your Mother creator Craig Thomas said. "I think that's part of what appealed to her."

It is Britney Spears' first return to the small screen since a 2006 cameo on Will & Grace... unless you count last fall's VMA live disaster.
