Meg Ryan, 55, absolutely stuns in sequins at the CFDA Awards

Nearly every designer that hit the red carpet at the 2017 CFDA Awards on Monday night had a very famous date -- and Christian Siriano's was the stunning Meg Ryan.

In what's being called a "surprise appearance," the 55-year-old actress turned heads for all the right reasons in a sexy white, sequined dress by Siriano. She kept the rest of her look just as simple, accessorizing with a diamond bracelet, natural makeup (she was glowing) and relaxed ringlet curls.

See the flawless look:
