The former Waterloo Road star is now back in drizzly England but last night treated fans to a new snap taken on the Caribbean island.
Chelsee is posing on tiptoes on the balcony of her hotel in the picture and is showing off her natural curves in all their glory in a leopard print bikini.
Sharing the photograph with fans on Twitter, she simply said: "JA." We think Kim Kardashian would be jealous of that derriere!
Chelsee also posted a selfie on the social networking site, which showed her pulling a pout and sporting a pretty red flower in her hair.
"Freckle face! Wish I was back in Jamaica :(," she added.
Chelsee spent 10 days in the Caribbean and flew home on Sunday (24 August), but unfortunately she is still feeling the effects of the time difference.
Last night, while struggling to nod off, she complained to her followers: "Jet lag you are horrible :(."
Coming home wouldn't have been so bad if the weather here was nice, eh Chels?!
