Heading straight to the pool almost as soon as the plane had landed, the 36-year-old Coronation Street star proved that the Spanish hotspot isn't just the holiday destination for the stars of The Only Way Is Essex.
After topping up her tan, Kym dressed up in a gorgeous black gown for dinner with her best girls at a local restaurant.
Kym's hens included fellow Corrie star Beverley Callard, former Emmerdale star Sheree Murphy and Jamie's sister Charlie Webb, who plays Debbie Dingle in Emmerdale.
Kym has been dating ex-Hollyoaks actor Jamie for 4 years and they have a 16-month-old daughter together called Poppy.
The couple are due to say their vows in September at the luxurious Nunsmere Hall hotel in Cheshire, and Kym's hen do was the perfect way to celebrate.
We even hear she was made to wear bunny ears, a necklace made of shot glasses and a "bride-to-be" sash at one point!
Arriving home in the UK, the actress tweeted: "Had THE most amazing weekend thanks to the best friends and family a girl could wish for!! Love you all more than the world xxx"
