Mark returned home after attending the same bash as Lucy in Los Angeles
The couple have furiously denied claims that Michelle, 29, was upset about Mark hitting the same fashion event as Lucy in Los Angeles earlier this month, with a source claiming that he flew back to the UK just a few days later to settle the disagreement.
Reps for the pair have insisted that there was no row and say that Mark, 30, had long planned to return to Britain to promote his latest show Take Me Out: The Gossip.
‘This story is complete nonsense,’ a spokesperson tells MailOnline. ‘Michelle was not remotely upset about Mark being at a party in LA.
‘Mark was always going to fly back to the UK from LA to complete pre-agreed promotion for Take Me Out The Gossip.
‘This was planned weeks before and viewers will have seen him live on programmes such as Lorraine that week.’
It comes after an insider alleged to The Sun that Mark – who was in the US to meet with TV executives – upset his wife when he was seen with Lucy, 25, at the Pretty Little Thing event across the pond on 11 April.
‘They were just talking, nothing happened between them,’ the source claims.
‘But when Michelle realised he had been socialising with Lucy a few days later, she wasn’t happy – and by April 15 he was on a plane home.
‘Mark flew into London, not Tenerife, where they film the [Take Me Out: The Gossip] Fernandos scenes.
‘It was an unusual trip given he flew back to LA days later.’
Mark used to date Lucy back in 2011 during the first series of TOWIE before he reunited with on-off flame Lauren Goodger.
In late 2012 he met Michelle and they announced their engagement in September 2013. They went on to tie the knot in May 2015.
Meanwhile Lucy had an ill-fated engagement to Mario Falcone and enjoyed a romance with gymnast Louis Smith after leaving TOWIE, though they broke up in February 2016.
