On April 23, supermodel Gigi Hadid celebrated her 30th birthday.

It made her younger sister Bella Hadid extremely happy. She posted on Instagram pictures of her sibling, her niece Khai (Gigi and Zayn Malik`s daughter the couple is now separated) with the caption: `You are the most funny, cool, fun, creative, artistic, loving, thoughtful human/big sis, and to watch you be the best, most fun, bad ass mama to our Khaiba is the greatest gift to me as a sister. . .

You have taught me so much of how to be myself in a world of people telling us all who we are supposed to be. And that`s a gift I cherish from you beyond anything.` Bella G, we`re glad you`re you too.
