“I would have to say the only thing missing from my amazing birthday party was my siblings,” Hannah told the outlet. “I miss them and I know if we got to spend more time together, especially on our birthday, it would be more fun.”

She chose to celebrate her first year of adulthood in Miami because she plans to study business at a Florida college, according to Page Six. Her interest in business stems from her beauty and cosmetic line, Gosselin Girl, which she launched the same day as her birthday with a series of facial serums.

“I seriously can’t believe I am 18!” she said. “It feels like yesterday when my brothers and sisters and I were all together shooting the show! I don’t miss it, but I miss them! I’m really excited to be at this point in my life.”

She added, “I feel a certain type of freedom.”
