"Happy 18th Birthday my sweet angel, thank you for all the light you bring into my life, you inspire me to be the higher me," The Real Housewives of Beverly Hills mom shared on Instagram, along with an adorable baby photo of Anwar. "Your kindness and consciousness is the greatest gift I treasure everyday so thank you for all that you do and all that you are to me and your sisters."
Big sister, Gigi Hadid, was so excited for Anwar's bday that she posted an all-caps message for her younger sibling. "18 YEARS AGO MY LIFE WAS BLESSED W THE MOST SPECIAL AND AMAZING LITTLE BROTHER ON DA PLANET," she wrote, also sharing a couple photos of her with him. Because nothing says love like all caps.
The middle of the globe-trotting Hadid siblings, Bella Hadid, also had a message for the youngest of Yolanda's brood. "Your love and light is worth all of the stars in the sky! I'm so proud of the man you have become and are becoming. I'm so proud and lucky to call you my brother," she wrote. "Nobody loves you more than me my mini me."
