They're getting so big! Sarah Jessica Parker's twins made a very rare red carpet appearance with their famous mom on Thursday, May 3 — and eight-year-old Tabitha and Marion Broderick look so grown up in the new pics.

For the fun outing at the New York City Ballet's Spring Gala, SJP's girls looked adorable in pretty spring floral dresses and matching white shoes. Watch the video below to see the new pics of the Broderick girls!

The 53-year-old Sex and the City star and her husband Matthew Broderick, 56, welcomed their twin girls via surrogate in June 2009. The longtime couple are also parents to a 15-year-old son named James Wilkie Broderick, who Sarah Jessica gave birth to in October 2002.

Though it's very rare for any of Sarah Jessica and Matthew's three kids to hit the red carpet with their parents, the trio did step out for the Broadway premiere of Charlie and the Chocolate Factory in April 2017.

Last year, the proud mom documented her family’s trip to the Lunt-Fontanne Theatre in Times Square for the special Broadway premiere with a cute Instagram video. While the family-of-five rode in the car to the event, Sarah Jessica sang along to Sly & The Family Stone’s 1971 hit "Family Affair." She captioned the clip, "Yipee! On our way to see Charlie and the Chocolate Factory and the whole family [gets] to go and cheer for our dear [Scott Wittman] and [Marc Shaiman]."

After the show, Sarah Jessica returned to Instagram to share a photo of her Broadway playbill and gush about her family's experience at the theater. "A lot of VERY happy people just left the Lunt-Fontanne Theatre in NYC. Count the Parker-Brodericks among them. Join the joy and be an audience at Charlie and the Chocolate Factory," she captioned the pic.
