"Bringing in my 3-0 in style at @OceanBeachIbiza with my girlies!!" Tweeted Jessica, who has played Nancy Hayton in the soap opera for eight years.
Joining Jessica at the pool were co-stars Bronagh, Jorgie, Jennifer and Biana who also slipped into an array of colourful swimwear for their sunny holiday. Jessica, whose birthday is on 19 May, sported an eyecatching black, orange and pink bikini with cut out detail.
Wearing a pair of bright red rimmed sunglasses, Jessica posed alongside her friends with her birthday cake and several celebratory drinks.
The stars let their hair down on the break from filming, enjoying the hot tub and sampling the cocktails on offer at the beach-side resort.
