‘She is the reason I joined the KB2 family, she welcomed me with open arms and love, she supported me, she pushed me, she made me laugh (like pee my pants laughter and had to check my underwear), she inspired me to be a bettter actor, she shared her family with me, THE LIST GOES ON. Grateful for you forever.’

Joey has also been sharing her birthday celebrations on social media, posting a humorous snap with her in an empty bathtub filled with balloons, while holding a bottle of champagne.

She also shared some bikini snaps on the beach and even a ‘transformation’ photo that shows what she looks like as an old, balding, bearded man. 

While the actress was largely obscured by the large balloons in the tub, she was wearing a tiara on her head with a white top.

One of the photos showed the jubilant actress popping the bottle of champagne with large 21 balloons floating above her.

Her birthday comes just days after the release of her new Netflix film The Kissing Booth 2, and the actress confirming a third movie.

Joey was part of a live-streamed fan event for The Kissing Booth 2, alongside Taylor Zakhar Perez, Maisie Richardson-Sellers and Meganne Young last Sunday.

The cast members had a few surprises for the fans, one of them being that The Kissing Booth 3 has already happened, and it’s already been shot.

The actors revealed that they had actually shot both The Kissing Booth 2 and The Kissing Booth 3 back-to-back last summer, with the film arriving in 2021.
