Julia Roberts has shared a rare snap of her twins, Hazel and Phinnaeus, in a sweet tribute for their 17th birthday.

Taking to Instagram, the Pretty Woman star wrote, “Seventeen of the Sweetest years of life” along with 17 birthday cake emojis to accompany a throwback photo of the twins as babies.

Her husband, Danny Moder, also took to social media to celebrate the special occasion. He shared a more recent photo of the pair, writing, “These rabble rousers. 17 today. Thank you for helping me through fatherhood.”

Julia and Danny have kept their personal lives far away from the spotlight, and their daughter Hazel made her first red carpet appearance at the Cannes film festival earlier this year. Dressed in a pastel yellow long-sleeved dress, Hazel made the rare appearance in celebration of her Danny’s movie Flag Day, which also premiered at the festival.

The star couple recently marked another family milestone, with Danny posting a photo from the early days of their relationship to celebrate their 20th wedding anniversary.

“Today we start our 20th year of marriage,” Danny began the caption. “This photo was on a dusty road before that big idea … just holding on to this beautiful girl one day at a time. One epic day at a time.”

Danny and Julia were married on July 4, 2002, after first meeting on the set of Julia and Brad Pitt’s film The Mexican.

In 2004, the couple welcomed Hazel and Phinnaeus into the family, before having their third child, Henry, in 2007.
