Made In Chelsea star Reza Amiri has split from girlfriend Ruby Adler over claims she cheated, MailOnline can reveal.
The couple, who have been in an on/off relationship for ten years, had committed to each other for the long term during the latest series of the E4 show, which aired last month.
But just days after the season wrapped in April, Ruby flew to Los Angeles where she spent time with multimillionaire luxury real estate agent Gavin Rubinstein, whom she was pictured with in the front row at an LA Lakers game.
To her boyfriend Reza's shock, Ruby had struck up a close friendship with Gavin, famed for his appearances on Australian reality show Luxe Listings Sydney, despite the couple still being in a relationship and planning for their future.
Ruby, 30, and Gavin, 34, were also spotted looking close at the Beverly Hills Hotel during the reality star's trip to Los Angeles, sparking speculation they were dating.
Reza, 38, only discovered the betrayal weeks after Gavin posted an image of him with Ruby on his Instagram profile, which showed them at the LA Lakers game, sat next to A-list actor Jason Segel.

A source told MailOnline: 'Rez was completely devastated. Obviously, there's the embarrassment of something like this happening behind your back, but he also saw a future with Ruby, all he wanted was for them to settle down together.
'They have had a long and complicated relationship, but the hope was that they could put the past behind them and commit for the long term.
'Ruby's actions in Los Angeles went against everything they had discussed as a couple and Rez has been humiliated.
'Even after Ruby's trip to LA with Gavin in April, Reza believed everything was fine between them as they celebrated their May birthdays together alongside their respective families.
'The worst part is the likelihood the whole sequence of events will become a storyline on Made In Chelsea and he'll have to relive the trauma again.'
Posting on Instagram in April, Ruby shared a series of pictures from her LA trip, posing on Rodeo Drive having purchased a new handbag. She captioned the upload: 'Life is good.'
The highs and lows of Reza and Ruby's relationship have played out on Made In Chelsea over the years, with the couple struggling to cut ties whenever they separated.
They have both dated their fellow Made In Chelsea co-stars, with Reza romancing Love Island's Tina Stinnes and Ruby had a brief fling with Miles Nazaire.
MailOnline has contacted Reza and Ruby's representatives for comment.
