Love Island couple on the rocks as they have blazing row on boozy night out

LOVE Island's Ronnie Vint and Harriett Blackmore have sparked speculation they're on the rocks after having a blazing row on a boozy night out.

Just last week, The Sun revealed they'd secretly split before patching things up on the same day.

Footballer Ronnie, 28, reassured fans they were back on by posting a week-old picture of them together.

But, now it appears their relationship's in trouble again.

The sportsman was overheard on the phone to Harriett, 24, arguing at his launch party last night, which was attended by the likes of Joey Essex, Jessy Potts, Ciaran Davies and Nicole Samuel.

The bash, held at London’s trendy rooftop bar Jin Bo Law, marked the official launch of his new events brand, Eggi Boff.

Ronnie was audibly fuming with Harriet, who didn’t arrive until after 11:00pm with fellow islanders Matilda Draper and Uma Jammeh.

The event stared at 7:00pm and Ronnie was heard shouting: “It’s a liberty,” down the phone, adding: “Imagine what would happen if I never came to your even."

Harriet had been partying in Ibiza all weekend with the girls and missed her flight back to the UK on Tuesday morning.

Therefore, she had to book alternative flights which made her late to Ronnie’s party.

The dancer did not post from the event, nor did she feature in any of her boyfriend's.

Ronnie, who is nicknamed Turbo Ronnie, was accused of cheating on Harriett last month - just days after leaving the villa.

We told how he'd been spotted with a stunning teacher, 21, after a night out in Milton Keynes at city hotspot Blossom Room. 

Harriett appeared to ignore the claims - as he defiantly shared a snap of them together with the caption "winning in our eyes".

She looked incredible as she shared pictures wearing a plunging black dress last night, as Ronnie commented: "Baby girllllll loooking crazyyy."

The Sun has reached out to Ronnie and Harriett's reps.
