In an episode set to air May 12, Britney Spears
will reprise her role as Abby, producers officially announced Monday. Titled "Everything Must Go," the episode finds Spears and Neil Patrick Harris
's character, Barney, flaunting their "relationship" in front of Josh Radnor

Earlier this month, PEOPLE reported
that Spears would return to the sitcom after charming the cast and crew. A show source described Spears's return as a "mutual decision to work together more."
In a new statement, How I Met Your Mother
's executive producer and co-creator Craig Thomas said, "We're all so thrilled to have Britney joining us once again. And just to head it off at the pass this time around: Yes, Mom, Britney's very nice and no, I can't get her autograph for you."
Spears's initial guest turn -- on a March 24 episode -- earned critical praise and the show's highest ratings.
