Pals of Ashton Kutcher have declared he plans to marry girlfriend Demi Moore in May - despite the actor publicly denying they'll wed anytime soon. The friends also add that Kutcher, 25, and 41-year-old Moore, who have been dating since April, are in a hurry to get down the aisle because they want to start having children together. A source says, "Ashton and Demi agreed to wait until they had been together for a year before getting married. The wedding will be a big family occasion, not a circus. This is the opposite of some crazy Britney Spears coupling. They are mature, sensible people and are going about it in a very smart way." The pal adds that over Christmas, "Ashton gave Demi a promise of marriage, along with a 19-carat diamond tennis bracelet that's worth around $17,000. Demi was ecstatic." Sources tell America's Star magazine that the couple have also included Moore's daughters from her marriage to Bruce Willis - Rumer, 15, Scout, 12, and Tallulah, 10 - in the wedding plans. The friend explains, "They have had family counseling and have listened carefully to the concerns of Demi's girls. The girls were encouraged to speak frankly. Fortunately, they love Ashton and appreciate how much he and Demi love each other. Bruce has (also) given his blessing."
