The TOWIE co-stars are thick as thieves both on-camera and off, so Georgia made sure to publicly wish her bestie a very happy birthday on Friday (3 June).
Georgia wrote on Instagram: "Happy birthday to my beautiful @xkatiewright who has the best boobs in the world.
"The min this girl rocked up in Marbella with her little waist & big attitude I knew we was going to be friends. I have never known someone who thinks the same, acts the same, loves dogs the same, we are just the same person! The boys do call us the evil twins.
"I hope you have the best day & I can't wait to celebrate next week .. Thank you for always having my back! Love you lots (sic)."
Kate turned 25 today and was inundated with well wishes from TOWIE co-stars, friends and family. She's having a big party on Saturday night with co-star Chris Clark, who celebrated his 22nd birthday today, at the plush Café de Paris in London.
