Milania Giudice has officially entered her tween years. On Thursday night, Teresa Giudice and her The Real Housewives of New Jersey daughters gathered to celebrate little Milania's big 11th birthday. And, while the celebration looks like it was a low-key, family-only affair, love for the youngest Giudice girl was definitely an unofficial theme for the night, with Teresa dubbing her "#myheart."

Big sister, Gia (who recently celebrated her Sweet 16), also posted a loving message with a photo from the party. "Happy 11th birthday sissy," she wrote. "Love u endlessly. Keep making us laugh."

Teresa also reminded us all just how big Milania has gotten with an adorable montage video of some highlights from her daughter's life. "I can't believe how my bright eyed beautiful baby has blossomed into a confident strong young woman!" she wrote. "I love you Milania - Happy 11th Birthday! Thank you for always keeping us laughing!"
