The actress had been embroiled in a bitter custody battle with the actor since their marriage ended in 2006, but says they have attempted to patch up their differences for the sake of their daughters Sam, five, and four-year-old Lola.
She said: "I'm on speaking terms with Charlie because I don't want our bickering to affect our kids."
Despite their acrimonious split - which saw Denise file for a restraining order after alleging Charlie made death threats against her - the
star insists it hasn't put her off marrying again.
She added to Britain's Closer magazine: "My parents are still together, so I know marriage can work. I'd definitely walk down the aisle again. "I'm looking for someone secure and funny to have more kids with."
