From Olivia Newton John to Beyonce's mother Tina Knowles, check out the sexiest ladies all over the age of 50!

The mother of Gwyneth Paltrow, Blythe is no stranger to acting and has racked up Emmy and Tony Awards throughout her career! She's just a few months away from the big 7-0, but you would never know it from the way she looks on the red carpet.

Tina became a grandma at 50 years old by her youngest daughter Solange back in 2004, and was made a proud grandmother once again earlier this year with the arrival of Beyonce's first child, Blue Ivy Carter. Her work as the costume designer for both her daughter and formerly Destiny's Child definitely shows with the always trendy and occasionally revealing outfits she wears on the red carpet!

Known as "Daytime's Leading Lady," Susan ended her 31-year run as Erica Kane on All My Children last year. Even though we've watched her on the soaps for six decades, it seems like she's barely aged!
