Sarah Jessica Parker is one proud mom.

The 51-year-old actress took to Instagram to share a sweet message for her twins, Loretta and Tabitha, who turned seven years old on Wednesday.

"Happy birthday to our lovely, funny, dear, surprising, sparkling and beloved Loretta and Tabitha who today are 7 years old," Parker captioned a pic of her daughters excitedly playing in a grassy field. "Let the celebrations begin. X, sj."

Parker and her husband, actor Matthew Broderick, welcomed their adorable twins via surrogate in June 2009. Loretta and Tabitha joined their older brother, the now 13-year-old James. Last October, she celebrated her eldest child's birthday by also Instagramming rare family photos.

Parker opened up to ET in February 2014 about her daughter Loretta, when we chatted with the Sex and the City star about her shoe line at Nordstrom. Parker revealed that Loretta definitely takes after her famous mama when it comes to her love of high heels!

"Actually the first time Loretta put on a pair of my shoes, I was like, 'Wow, I can't believe this is really happening,'" Parker recalled, smiling. "There are those little feet in my shoes -- those sort of images that you think are sort of cliche, but then you're seeing them shuffle around, you know, not picking their feet up but doing that shuffle in your shoes, and it was kind of tender."

Of course, she definitely has her limits when it comes to playing with her pricey heels.

"It was kind of sweet, then I was like, "No, be careful with that pair!'" she joked. "Oh God, be careful!"
