Why are we SO annoying. Birthday eve eve.
The actress then posted another series of pictures with her co-stars.
She captioned the post: "Album cover."
Fans loved seeing the Emmerdale cast together outside of the soap.
One wrote: "Awww nice to see all of you out and living the real life instead of being on camera. Well... a bigger camera.
A second commented: "Dream team. Wish I was a part of your gang."
A third added: "Oh I love you all so much, you are the best."
She later posted a picture with Laura and called her her "soul mate."
Isabel deserves a night to enjoy herself as she's been working hard on one of Emmerdale's biggest storylines this year.
Soon afterwards, Victoria discovered she was pregnant with her rapist's baby, but came to the decision she wanted to keep her child.
When Lee and his mum Wendy discovered the chef was pregnant, they began harassing her for rights to the baby.
But eventually, Victoria's brother Robert was pushed too far when Lee admitted to raping victoria and hinted he would do it again to other women.
Emmerdale airs weeknights at 7pm on ITV, with an extra episode at 8pm on Thursdays.
