It's hard to believe, but Real Housewives of New Jersey star Dina Manzo's daughter, Lexi Manzo, is all grown up! The Jersey girl turned 18 this Saturday, January 26, 2014, which means she's officially an adult.

While it's been cool for Real Housewives of New Jersey fans to see Lexi go from cute young teen (even though she claims she was “awkward”) to totally confident young adult, that's obviously nothing compared to how her mom must feel to see her baby bit the big 1-8.

In fact, Dina celebrated the day by posting this awesome montage to Instagram and we totally love it. The pics of Lexi as a tot on the left could not be more adorable, while the two current pictures on the right show how that little girl has grown up into a really beautiful young woman.

Dina also had a heartfelt message for her daughter:

"I wanted her to stay little forever...but my baby girl is 18 today. I love you Lex to the moon & back! Thank you for choosing me as your Mama! I'm so proud of the kind compassionate witty young lady that you are! Happy Birthday!!!"

Aww! Happy Birthday, Lexi!
