Dame Shirley Bassey and David Walliams are in love! The romantic revelation is made tonight when the legendary singer and the comedian start flirting on The Graham Norton Show (BBC1, 10.35pm)

“I love him, but he is married,’ said Dame Shirley, regretfully.  “We’ve been in love forever, but then he got married. It was very cruel.”

David then replies: “I didn’t know you were available,” to which Dame Shirley responds cryptically, “When you kissed me, you didn’t know I was available? Is your wife here?”

David is forced to admit: “No, she’s actually not here, so…”

Their flirting continues when David then serenades Dame Shirley with a rendition of her James Bond hit Moonraker.

After the banter dies down, Dame Shirley also goes on to talk about her upcoming appearance on Strictly Come Dancing in Blackpool where she’ll be singing another of her Bond hits, Goldfinger, on the Sunday results show (BBC1, November 16, 7.20pm).

She last appeared on Strictly in 2012, with Ian Waite and Natalie Lowe dancing to her song This Time, but she admits having dancers in front of her can be annoying…

“The first time it was very disturbing and quite off-putting. I kept saying to myself, ‘Don’t look at them!'”
