Washington, Apr 22 (ANI): Speculations about pop star Britney Spears doing another episode of 'How I Met Your Mother' have been dismissed by a source close to her.

The source revealed that nothing has been signed and no script has been written as yet.

The insider added that the singer would not be committing to anything at present.

"Nothing is signed yet," Usmagazine.com quoted the source as saying.

"No script has been written and until that is done, Britney will not be making a commitment. The offer is there but no decisions have been made at the moment," the source added.

The 26-year-old singer had appeared on the March 24 episode of the CBS comedy where she played Abby, a receptionist at a dermatologist's office who falls for architect Ted (Josh Radnor) when he comes in to have a tattoo removed.

There were no comments from CBS regarding her returning to the series. (ANI)
