The couple addressed their furious clash on the plane home in the ITV2 show’s reunion episode.
Host Maya Jama quizzed them on reports they had a tricky flight home.
And the pair admitted it wasn’t all plane sailing.
Lana told Maya: “It looked worse that it was.”
Things between the pair were so bad that they spent their first night back in the UK apart.
An onlooker said: “Lana and Ron had a furious argument on the plane home – production crew had to step in and calm it down.
“They were so fuming they refused to film the ‘meeting the family’ part of the reunion show at Heathrow until producers stepped in again.
“They were due to stay overnight in London together but after the fight they went back to their family homes separately to cool down.”
