Elizabeth Hurley's Son Damian is All Grown Up — See the New Photos! - Closer Weekly

Elizabeth Hurley may have looked red hot at the London premiere of her new show ‘The Royals,’ but her best accessory was her son, Damian!

For the occasion, Damian — who will turn 13 next month — wore a dapper black suit with a purple tie while his famous mom, 49, donned a figure-flattering red dress designed by Versace.

Elizabeth welcomed Damian, her only child, in April 2002 with her then-boyfriend, businessman Steve Bing. The child’s Godfather is none other than the actress’ ex Hugh Grant, whom she dated from 1987 to 2000.

On ‘The Royals,’ the star portrays Queen Helena, the devious matriarch of a fictional British royal family. During a recent talk show interview, Elizabeth revealed her son spent a lot of time hanging out on the set of the E! show during its filming last summer.

“During his vacation from school he was on the film set and he loved every single second of it. He adores it. He really wants to do it,” she told ‘This Morning,’ referring to her son’s interest in working in the film industry.
