NEW YORK - Britney the Trainwreck has shown she can still be Britney the Performer.

Britney Spears made her much-hyped guest appearance on Monday night's "How I Met Your Mother," submerging her tumultuous personal life and portraying a sweet-natured receptionist, Abby, with a crush on unlucky-in-love Ted (Josh Radnor).

The 26-year-old pop star, who previously was on a 2006 episode of "Will and Grace," appeared fresh-faced and relaxed, capably filling the small role.

Of course, she's made news in recent months not for being Britney the Performer but for her split with ex-husband Kevin Federline in late 2006, their subseqent custody battle, Spears' bizarre behaviour and two hospitalizations.

Spears' cameo on the CBS sitcom may mark the beginnings of a more successful comeback attempt than last September's MTV Video Music Awards.

She remains under the conservatorship of her father, James.
