The Osmonds have been in the spotlight for 50 years but family has always been their number one priority, and George and Olive started it all. Their 60-year romance began on a dance floor during WWII. Marie and her Dancing with the Stars partner Jonathan take the stage to perform a tribute to her parents' love by dancing to "Boogie Woogie Bugle Boy."

At 48 years old, Marie shows she's in great shape—and her dancing brings a stronger message as well. "I did the show initially for my kids. But for women who find themselves like me, a single mom, you know, at 48…life is not over. I would rather climb a mountain than crawl in a hole," Marie says.
