Joan Collins and Stephanie Beacham reunite for Snickers advert Miss Collins, 78, and Miss Beacham, 64, will go head to head for a TV advert for the chocolate bar Snickers. Miss Beacham, who took part in the BBC's Strictly Come Dancing in 2007, will also throw a tantrum about being substituted during a match. Miss Collins said it was her suggestion to approach her on-screen arch-enemy to take part in the advert, replacing the A-Team's Mr T as the face of the chocolate bar. "When they said, 'we need a similar lady to come on and be another diva," I said, 'well, there's only one choice - Stephanie'," she said, according to the Daily Mail. I mean, we had so much fun on Dynasty.
