If HOW I MET YOUR MOTHER gets renewed for a fourth season, fans may have… wait for it… Britney Spears to thank.
According to E! Online, and confirmed by MOTHER Masterminds Carter Bays and Craig Thomas, Spears will appear as a guest star on the show’s fourteenth episode of the season playing a co-worker of Teds.
Such stunt-casting worthy of well, Spears last TV sitcom gig WILL & GRACE naturally begs the question: Just how desperate are you to see HOW I MET YOUR MOTHER get picked up for a fourth season? Because this TV Addict will publicly pledge to buy tickets to a Britney Spears concert [assuming she ever performs again], should the inevitable ratings boost factor into HOW I MET YOU MOTHER getting renewed.
