It's been a long, long time since anyone asked Britney Spears for an encore, but the singer is reportedly planning on taking a second bow in her role as a [article id="1583848"]ditzy receptionist on the CBS sitcom "How I Met Your Mother."[/article]

After her first appearance on March 24 catapulted the comedy to its best ratings ever among viewers ages 18-to-49, Spears is scheduled to return to the show for another episode, according to People magazine.

"The show is ecstatic, and so is Britney," an unnamed source told the magazine. "She had so much fun the first time around, she really wanted to come back. It was a mutual decision to work together more."

It has not yet been announced when she will appear again as the motor-mouthed dermatology receptionist with a thing for mustaches and a crush on Josh Radnor's character, Ted Mosby, but co-star Neil Patrick Harris seemed to confirm the news to MTV News on Sunday at the New York Comic-Con.

"She's coming back again, so I hear, so it should be fun," the "Harold & Kumar Escape From Guantanamo Bay" actor said. He added that his enthusiasm is not exactly a reversal from [article id="1585187"]the comments he made two weeks after Spears first appearance on the show[/article], when he said he doubted that Spears, 26, would join the ensemble as a recurring character. "The media takes things out of context and makes other stories out of them, which was pretty much that in a nutshell," he said in reference to his previous statement.

"She's not an actress," he told MTV News earlier this month. "She played a role for a week, and did a really nice job, but the workload involved with doing memorization and the purging of comedy over and over is really, really hard. I mean, it takes a strong skill set to do that every week."

Earlier this month, TVGuide.com learned that Sarah Chalke, who played Spears' boss on the show, would return as Ted's love interest for a few episodes, making Spears' return also seem likely.

However long her story arc on the show lasts, the positive reviews and steady work could help Spears get her career back on track after several years of personal struggles and professional setbacks.
