Actress Julia Roberts shared a rare photo of her twin sons, Hazel Patricia and Phinnaeus Walter, on Instagram to celebrate their 19th birthday. The photo, which is in black and white, shows the twins as babies while Julia holds one in each arm. The actress, who shares the twins with her husband, Danny Moder, also has a 16-year-old son named Henry Daniel. Roberts and Moder met on the set of the film The Mexican in 2000 and were married in 2002. While the actress tends to keep her children out of the public eye, she couldn't resist posting a loving tribute to her sons on their special day. In addition to the photo of her twins, Julia's Instagram account is filled with promotions for her new film, Leave No Trace. The actress is now able to promote the psychological horror film, which was released on Netflix, following the end of the actors' strike.
