Veteran actress Joan Collins has revealed that sex is the biggest thing that has kept her 12-year marriage to husband Percy Gibson strong.
When the 'Nutcracker' star was asked on Britain's 'Loose Women' what the top three most important things in her relationship with Gibson are, she simply said "sex, sex, sex," the Huffington Post reported.
The couple tied the knot 17 February 2002 and later renewed their vows in 2009.
