..They've barely set foot on English soil after a whirlwind trip to Marbella which saw them become engaged.
Yet it seems Lucy Mecklenburgh and Mario Falcone couldn't bear to stay out of their swimwear for more than a few weeks.
The couple looked besotted as they embraced while enjoying a break in Dubai.
Lucy showed off her incredible figure in a halterneck bikini as she dried off in the sun after a dip in the pool.
Embraced his bride-to-be: Mario Falcone leaned in to kiss his fiancée Lucy Mecklenburgh during a recent break to Dubai
The 20-year-old also flashed her gigantic engagement ring from Mario- which she thoughtfully teamed with white nail varnish.
It appears that the pair can hardly bear to be apart for even a few hours.
Lucy tweeted this morning: 'Morning !! Im off to a shoot today gutted I will miss @Mario_Falcone on loose women .. Good luck bub x'
Mario proposed to Lucy on a yacht during their recent trip to Marbella.
The reality star told her: 'I can't put into words how much I love you', before adding: 'In the words of Michael Jackson you rock my world.'
He added: 'I don't know what we will be doing in 50 years time but as long as I'm with you I really don't care.
He told her: 'Make me the luckiest guy in the world, will you marry me?'
Lauren Pope recently commended Lucy and other young TOWIE stars on their composure considering their rise to fame at such a young age.
She said: 'Everyone is coping pretty well like considering they're getting all this fame at 20/21.'
Can barely keep her clothes on: With a figure like that, no wonder Lucy's always so keen to get into her bikini
'If I had it at that age I would have turned into a big nightmare I think they're doing a good job.'
Lauren added: 'Me and Chloe because we're a little bit older we're more laid back we tend not to get caught up in the drama.'
'I like it that way, we'd rather just have jokes and have fun.'
Can't keep their hands off each other: Lucy and Mario can hardly bear to be apart
