Gigi’s Birthday Wish For Bella Hadid’s 21st Proves They’re The Cutest Sister Duo!

Gigi Hadid has praised her younger sister Bella as an inspiration as the brunette beauty celebrates her 21st birthday. The 22-year-old older sister took to Instagram on Monday (09.10.17) to celebrate her sister and fellow model hitting the milestone age of 21, and in a sweet tribute, she claimed she is “so so proud” of her “forever cool” sister.

Posting a throwback picture of a young Gigi feeding Bella her bottle, she wrote:

The post comes after the blonde beauty – who is in a relationship with Zayn Malik – took to the photo sharing website the day previous to remind her followers that her “forever bestie” would be turning 21 soon.

Gigi isn’t the only member of the Hadid family to send her well wishes to Bella on social media either, as their younger brother Anwar, 18, dubbed the brunette as “the best sister ever”.
