Julia Roberts, 55, the star of 'Ticket to Paradise', now has two young adult children as her twins Phinnaeus and Hazel turned 18 on November 28. The actress posted a throwback picture of her with the twins as toddlers and captioned it with, "18 Love you." Roberts was seen holding one of the children up and exclaiming in shock in photo. She was sporting a dress with the strap on one shoulder falling down and an easy yet stylish updo with her brunette hair.

Roberts restricts comments on her Instagram but many famous personalities, including singer Rita Wilson, took to the comments section to wish the twins a happy birthday, Hollywood Life reported. "It can't be!!!!!!! Happy Birthday!!!!" Wilson commented. Celebrity stylist Elizabeth Stewart also commented, "Happy birthday kiddos!!!" Other accounts also chimed in, with one writing, "Finn and Hazel, the most perfect duo."

Finn and Hazel's birthday occurs precisely one month after Roberts posted on Instagram to honor her own birthday on October 28. The Oscar-adorable winner's selfie was captioned, "Feeling the love and magic on my 55th birthday. My cup runneth over." Wilson, Tom Hanks' wife, also left a comment on this post to wish her closest friend on her special day. "Happiest of days, sistah Scorpio! Sending you love, love, love," she said alongside a string of heart-shaped emojis in pink and red.

Roberts discussed her long marriage's secret with E! News shortly before turning 55. The rom-com actress said, "I always say that same thing, and I'm sticking with it. It's making out. A lot of making out." The 'Pretty Woman' actress also revealed to the publication that her family is her concept of paradise. She gushed, "That's our paradise. That's how we both feel." Daniel Moder, 53, and Roberts have been married for more than 20 years. On July 4, they commemorated their 20th wedding anniversary since tieing the knot in 2002. In a flashback shot of her and Daniel kissing, she wrote, "TWENTY #can'tstopsmiling #can'tstopkissing."

Moder and Roberts also have a 15-year-old son named Henry Daniel together aside from their twin children. The mother-of-three and her co-star George Clooney, 61, attented an interview with People last month to talk about their movie, 'Ticket to Paradise', and parenting styles. "It's just the expansion, being together while our lives expand in these beautiful ways," Roberts said of her friendship with her co-star and good friend. "We are kind of the same goofy nuts that we've always been, and now we have these incredible people and these beautiful families," she added.

She continued by saying that she was "so happy" for George, who married Amal Clooney in 2014. On the other hand, George also disclosed that Hazel, Roberts' daughter, occasionally calls Amal for guidance. He continued, "It's also fun to see your kids turning into adults," while Roberts added, "Crazy."
