Rihanna shows off bikini body celebrating Christmas in Barbados

While we're tucked up indoors away from this chilly British weather, the likes of Elle Macpherson and Rihanna have been sunning themselves in considerably warmer climes over Christmas.

And we're really wishing we'd thought to do the same.

After wrapping up her worldwide tour in London last week, RiRi took off home to Barbados to spend the holidays with her family - posting this bikini snap on her Twitter page.

"#BARBADOS" she Tweeted.

Cue envy. Not purely because we also want to be in Barbados right now, but because we wish we looked this good in a bikini. (Not helped by the fact we've eaten everything in sight for the past four days.)

"Barbados will always be home sweet home!!! I've been WAITING for this moment!!! I can't believe its real! My vaca starts in 3,2..." she Tweeted on Christmas Eve.

Followed by: "And the sun is back!!!! Time for me to lose this "Wednesday Addams" look I been rockin all tour!"

We're not quite sure we see the resemblance...
