Delilah's younger sister Amelia Gray Hamlin was also there to celebrate the big day. Of course, Lisa also couldn't believe that Delilah, who will be turning 19 on Saturday, has grown up right before her very eyes. "It happens so fast!" Lisa tweeted.
The RHOBH daughter has a bright future ahead of her. She's on her way to becoming one of the biggest supermodels in the industry, with editorial spreads in magazines like Teen Vogue and walking in New York Fashion Week in shows for Tommy Hilfiger and Sherri Hill. Delilah also recently rocked the red carpet at the CFDA Awards on Sunday, which her mom couldn't help but applaud via social media.
But then again, Lisa and her whole family have always taken amazing photos.
