The pop star continues her run on the CBS sitcom.

BRITNEY SPEARS' second appearance on CBS' "How I Met Your Mother" went off without a hitch on Monday night, with the pop star fitting right in with the show's masterful cast.

The episode, in which Britney continues to crush on the show's star JOSH RADNOR, featured a mock proposal to Brit from NEIL PATRICK HARRIS and left the door open for a possible future appearance.
