Alan Osmond, the eldest member of the chart-topping family act The Osmonds, died Monday after decades with multiple sclerosis. He was 76.
The special ceremony marked the actress' first public appearance since she shared her multiple sclerosis diagnosis last year.
"It burst my heart open," Blair said after her Viennese waltz brought the ballroom to tears.
Selma Blair is challenging herself by competing on "Dancing with the Stars." Her pro partner says her multiple sclerosis diagnosis makes things difficult, but she's persevering and inspiring others.
"May we find that strength to lift our heads up. Mine currently is on my pillow. But I try," she wrote.
"It's been a tough road. But as we all know, the road keeps going," the 49-year-old actress said.
