When Joan Collins tied the knot for a fifth time, to much-younger man Peter Gibson, many thought it would never last. But the ‘Dynasty’ actress says they’re happier than ever after seven years of marriage – and she even claims her 43-year-old toyboy has helped bring her family together. Joan (75) says, “I have three children by two previous husbands and it’s always been a bit fragmented, but Percy has managed to make our whole family meld into one unit. It’s all consolidated now. He’s the most wonderfully diplomatic and kind man. He’s wonderful and he genuinely loves them all.”
