ET has the latest clip of BRITNEY SPEARS from her second "How I Met Your Mother" appearance, airing on Monday, May 12 at 8:30 p.m. on CBS.

The pop princess, of course, will once again play Abby, the receptionist, who in this episode teams up with Barney (NEIL PATRICK HARRIS) to get back at Ted (JOSH RADNOR), who has started dating her boss (played by gust star SARAH CHALKE). Abby is upset because she believes that Ted is the love of her life.

"It's been great good times," Neil says of his new co-star. "Britney was relaxed and playful. She gave lots of choices, even improvised a bit. I suspect it'll be quite the funny episode."

Earlier, Britney had released the following statement on her return to the CBS comedy: "I had such a great experience the last time I was on the show that I couldn't wait to come back," she said. "I was really looking forward to working with this cast and crew again. Everyone was so nice. Abby is going to have a lot of fun!"
