Trouble before paradise? Marnie Simpson shocks onlookers as she has a blazing row with love rat ex Lewis Bloor... moments before they head on holiday together

Their relationship status has been at the centre of much speculation.

Startling onlookers with her furore, the 25-year-old reality starlet was seen screaming at her love rat ex - who she split from in February after it emerged he had cheated on her on Valentine's Day.

Whilst the pair have not spoken about their current relationship status, they are currently living together and appeared to be heading on holiday together before their row. 

Taking to Twitter on Tuesday, Marnie shared a sunshine and plane emoji, and just a few hours later Lewis posted on Instagram: 'Buzzing, just confirmed our holiday to @uniquecruise cant wait for a week of top deck pool parties and a 24/7 casino, and the most insane line up of summer.'

MailOnline have contacted representatives for Marnie and Lewis for comment.

Marnie's romance with former TOWIE star Lewis blossomed in their stint in CBB in July last year after which they professed their love - although admitted they were finding it hard to maintain their relationship due to the long distance.

After Marnie moved from her native Newcastle to London to be with her beau, it appeared things were back on track - until Lewis' cheating revelation.

The stunning brunette was left devastated when Lewis admitted he had doubted their relationship during a holiday in Barcelona - causing him to sneak out of their hotel room and kiss a girl on the beach.

That wasn't his only indiscretion, however, as video footage was leaked of the TOWIE bad boy in bed with a woman he had met earlier that evening whilst Marnie celebrated Valentine's Day alone. 

In a tearful Snapchat video, Marnie was seen crying after watching the footage, as she sobbed: 'I can’t actually believe it. I’ve cried, I’ve screamed, I’ve smashed my house up. Every emotion, I’m still in shock.

'I’ve never been cheated on until now, it’s the first time I’ve experienced what it feels like, it is awful, its horrendous. '

In a further shock twist, Marnie recently revealed she is still living with Lewis, telling Daily Star: 'To be honest things between me and Lewis are f***ed up and really complicated. We aren't back together, but we are still living together as we have just signed a new lease'.

She also admitted that they sleep in 'separate rooms', also continued: 'Obviously (we) aren't bringing anyone else back as that would just be weird.'

The pair were last seen together at a charity boxing match this month, with Marnie planting a kiss on her former flame to congratulate him on his win.

Clearly happy to move on with their friendship she was sitting ringside at the star-studded boxing match in which her former love was triumphant over Storage Hunters star Heavy D, with whom he had various rows in CBB.

Marnie's kindhearted words read: 'Well done @lewis_bloor it was a long journey with the best outcome! U did great ! #FightNight... Good luck tonight @lewis_bloor regardless of our ups and downs I still want you to win. You'll smash it #fightNight'.

Sources told The Sun: 'Marnie was trying to keep a low profile but she couldn’t hide her excitement at seeing Lewis in the ring. She’s had a tough few months with him but of course there are still feelings there – she was madly in love with him.
