Mom’s the word from royalty watchers this season. Princess Caroline of Monaco and hubby Stefano Casiraghi are expecting their first child “sometime this summer,” according to the official palace statement (June is the unofficial word from family friends), while in Britain the Prince Charles and Princess Di-nasty will grow some time in September.

Rumors of 27-year-old Caroline’s pregnancy began circulating before her December marriage to Italian businessman Casiraghi, 23. Even if the nine-month countdown comes up short, Caroline is said to be reveling in incipient motherhood, as is her father, Prince Rainier. The baby will be his first grandchild. A modern mother-to-be (although she hasn’t given up smoking), Caroline is planning on a natural delivery in the same room in the palace where she was born, which has been stocked with the latest medical equipment to cover any emergency. Friends say that if it’s a girl, the baby will be called Grace after Caroline’s mother. If the newcomer is a boy—a fact Caroline reportedly confirmed to intimates after she had had an ultrasound test—he will most likely be named Andrea after a friend of Casiraghi’s who died in an accident last year.

Meanwhile Charles, 35, and Diana, 22, claim they have no time to think about names for their second-born, what with the Princess having suffered from first-trimester morning sickness and 23-month-old Prince William entering the “Terrible Two’s.” Sighs Dad, “He breaks everything in the house.” The Prince is said to favor a girl, and William Hill, a chain of leading British bookies, was giving odds of 10-11 on a girl, 5-4 on a boy. The chain closed its books on April 1, because bets on twins (they run in Di’s family) suddenly soared, arousing suspicions that gamblers had obtained inside information. As for names, the parents may not know but the bookies say Elizabeth and Victoria and George and Richard are the faves. Whatever its sex, the new arrival will become the third in line to the throne, bumping uncle Prince Andrew back to fourth place.
