Sexy singer Beyonce Knowles' joy of landing a record deal with DESTINY'S CHILD was marred by sadness - because her parents split up.

The stunning SURVIVOR star, 21, shot to chart-topping fame in the late '90s when she and bandmates launched their assault on the R 'n' B market.

But Beyonce's parents MATTHEW and TINA, who serve as the group's manager and stylist respectively, had personal traumas which got in the way of her initial happiness.

She says, "At the beginning of Destiny's Child - when there was a lot of stress going around - my parents separated for a while.

"They couldn't live away from each other, and my dad finally moved back in with us for a few months. I definitely learned what it was like for two people to fight for their love.

"My dad is gentle but also tough when he needs to be. It's not going to be easy to find a man in my life - it's going to be hard to live up to my father. Because of him, I have standards."
