AceShowbiz - Gigi Hadid spent her 20th birthday on Thursday, April 23 working for a poolside bikini photoshoot in Miami, Florida. In some photos obtained by Mail Online, Gigi could be seen posing in three bikinis and two one-pieces for a Seafolly campaign.

The Sports Illustrated model wore a red bikini with white polkadots and high-waisted bottoms, a denim patchwork triangle bikini, printed bikini with black straps, a black backless one-piece and a coral one-piece with mesh details.

Gigi shared on Instagram a photo of some buckets of flowers and birthday gifts she received on the photoshoot set. "Feeling so loved and blessed today... I'm so lucky to have people in my life that make me feel at home even in a hotel! Thank you all, I love you!" she captioned it.

However, Gigi apparently wasn't fully happy as she lost her beloved dog on the same day. She posted a throwback photo of her with her dog Lucky when she was 9 years old side by side with a photo of her older self with the same dog. She wrote alongside the touching photos, "On my 9th birthday an angel came into my life... And on my 20th birthday, that same angel went to a place where he can watch over me a lot better. To an irreplaceable companion, Rest In Peace my angel boy."
