Bella & Gigi Hadid share birthday love for The Weeknd

The Weeknd, whose real name is Abęl Tesfaye, turned 26 on Tuesday, and some love from the Hadids surely made this day sweet.

The singer's girlfriend, Bella, who he just slayed the Grammy's red carpet with, called him her "favorite person on the planet" in this Instagram post, where the Grammy winner appears to be sipping champagne.

Bella's sister and fellow model, Gigi, also had a message for The Weeknd. Gigi affectionately called him "A" in her Instagram post that shows the two nuzzling. She also said:

"Thanks for lovin my sis like you do. You have so much to celebrate tonight, beyond proud of you!"

And what about the girls' baby bro, Anwar Hadid? He got in on the PDAs via social media too posting his own pic and writing:

"happy birthday and congrats to this young legend!! so much to celebrate tonight and even more in the future"
