LOS ANGELES, Oct 16 — Hilary Swank is preparing to become a mother for the third time at 52, just three years after welcoming twins — and the Oscar-winning actress has offered a touching message of hope to women who fear their chance at motherhood may have passed.

The Million Dollar Baby star revealed her pregnancy in a playful Instagram video on Wednesday, announcing that she and husband Philip Schneider are expecting another addition to their family in December.

Swank, who became a first-time mother at 48, already shares three-year-old twins, daughter Aya and son Ohm, with the entrepreneur.

But rather than make a conventional pregnancy announcement, the two-time Academy Award winner enlisted her family for a glow-in-the-dark dance routine.
