Happy birthday! Sarah Jessica Parker shared a rare Instagram photo of her twin daughters, Marion Loretta and Tabitha, on Wednesday, June 22, in honor of their seventh birthday.

“Happy birthday to our lovely, funny, dear, surprising, sparkling and beloved Loretta and Tabitha who today are 7 years old. Let the celebrations begin. X, sj,” Parker wrote in her caption of the pic, in which the girls run free in a grassy area.

The Sex and the City alum, 51, welcomed her daughters with husband Matthew Broderick via a surrogate in June 2009. During a 2011 interview with Vogue, Parker revealed her daughters’ different personalities.

“Tabitha’s very, very outgoing, but physically she’s very shy. She shakes in elevators; it’s very sweet, like Bambi. [Loretta] is pale, like my husband, with piercing blue eyes. But she’s physically bold,” she told the magazine. “I think it’s funny how much she looks like my husband, except then I look at Loretta and she has my husband’s mouth and sort of sad eyes, you know the kind that go down? The Broderick eyes. They both really look like him.”

The girls’ big brother is James, 13, who helps keep Parker young and hip.

In a September 2015 interview with Harper’s Bazaar, Parker recalled when her teenage son taught her what a meme was after her 2015 Met Gala Philip Treacy headpiece was mocked online.

“My son was like, 'Mom, you're a meme,’” she told the mag. “ I didn't know what a meme was!"
