Though don't expect Donna's future nuptials to be as grand as Prince William and Kate's royal wedding. The pretty blonde admitted: "The thought of a big wedding… I would rather just go for lunch!"

James, 29, and Donna, 36, who have been dating for over three years, reportedly rekindled their romance following a brief split. But Donna is giving nothing away.

"It amuses me on a daily basis that there is so much speculation about [us] being on and off," the actress said. "I just smile, go with the flow and think it's best not to challenge anything. I remain very private about that."
