Kristen Bell wished her friend a very happy birthday with a bikini selfie which none of her fans were expecting.
The Frozen star, 40, shared a snapshot alongside the birthday girl but they weren't sunning themselves on a beach in a tropical location… they were sitting on a bus.
Kristen and stylist, Nicole Chavez, looked to be on an adventure in a foreign country and appeared makeup-free and a little hot and bothered.

The actress captioned the series of photos, which included others of them in various far-flung destinations: "@nicolechavezstyle has been responsible for every LEWK I've ever had on a red carpet.
"She's a devastatingly talented stylist. We have travelled 9 countries together. She's goofy and kind and loyal and elegant.
"She once tried to tip me over while I was using a port-a-potty. I love you Nicole and I learn so much from you. I'm so happy to have you as a best friend. Happy birthday."

Nicole adored her famous friend's tribute and commented: "Ok I am now officially crying. Love you."
Kristen was clearly feeling nostalgic for her travels, with the COVID-19 lockdown having halted her travel plans.

Although she added: "We explained [to the girls] what COVID was and why it exists and we told them everything really early on and we just reminded them that we're luckier than most people and we have to do what we can to help others during this time."
