When Prince Carl Philip and Sofia Hellqvist tie the knot in Sweden's wedding of the year this Saturday, the prince's niece and goddaughter, Princess Estelle, 3, will likely have a starring role. To give the lavish nuptials on June 13 a personal family touch, the future queen is expected to be one of the ring bearers.

The little princess, who is second in line (after her mother) to wear the crown, has charmed Sweden with her sweet laughter and impeccable manners. She has been guided by her parents Crown Princess Victoria and Prince Daniel to always exhibit model behavior in public. And though the names of the ring bearer(s) won’t be revealed until the weekend, Estelle has been involved in rehearsals for the special day.

The royal couple has invited the world to their wedding on Saturday, June 13 through a live broadcast on SVT, starting at 3 p.m. (9 a.m. EST), with the ceremony starting at 4:30 p.m. (10:30 a.m. EST). Watch the festivities here, and see whether the little princess has a role, too: www.svtplay.se
