The 51-year-old actress
-- who wore a stunning gold J. Mendel dress to the event -- won for her role in Divorce
, making this her first People's Choice accolade and the first award she's earned since her time playing Carrie Bradshaw in the Sex and the City
TV series and film franchise.
"I felt like this invitation was about the chance to say thank you to people who have for many years -- and it's unbeknownst to me why -- but they really have been like my traveling companion," Parker told ET's Carly Steel of her win. "I felt that this was this opportunity, more than anything, just about trying to express my gratitude."
