ADD another brilliant guest star to “The Big Bang Theory” roster.

    “Hello Ladies” alum Stephen Merchant has booked a guest role on an upcoming episode of the CBS comedy, The Hollywood Reporter said. Additionally, “Manhattan Love Story” grad Analeigh Tipton will also appear in a season nine episode.

    While CBS has remained mum on who Merchant and Tipton will play, multiple reports that have surfaced following Episode 9 taping indicate both will appear in the episode and play dates for Amy (Mayim Bialik) and Sheldon (Jim Parsons), respectively. It is worth noting that Tipton — a former “America’s Next Top Model” finalist — previously guest-starred and played herself during a previous episode.

    “Big Bang Theory” showrunner Steve Molaro told The Hollywood Reporter at the start of Season 9 that producers planned to keep Amy and Sheldon apart “until the time feels right.”

    “Right now, the dynamic has been fascinating and interesting,” he said. “We’re seeing all new colors for both of them as well as the way it impacts the group. There’s not a set plan — we’re feeling this out along in same way Amy is.”(SD-Agencies)
