10.6M watch Spears on 'Mother'

LOS ANGELES, March 25 (UPI) -- More than 10.6 million people tuned in to see Britney Spears guest star on Monday's episode of the U.S. sit-com "How I Met Your Mother," CBS said Tuesday.

The network said Spears's appearance propelled the show to the highest adult 18-49, and adult 25-54, ratings in its three-season history, as well as its best delivery of this season in viewers.

The show stars Josh Radnor, Jason Segel, Alyson Hannigan and Neil Patrick Harris.

"Continuing his passionate quest to find the woman who will one day be his wife, Ted (played by Radnor) pursues his beautiful dermatologist, Stella. While Stella turns down his repeated efforts for a date, her office receptionist, Abby, becomes smitten with Ted," said a release announcing the installment earlier this month.

"Scrubs" star Sarah Chalke played the dermatologist, while Spears played the receptionist in the episode.
