Megan Fox and Machine Gun Kelly proved they were back on track as they stepped out in London together on Tuesday evening.

The couple put on a united display as they brushed off speculation over their on-off relationship.

Megan, 37, caught the eye as she went braless in a figure-hugging white crop top and high waisted black trousers which had a silver diamante chain.

The actress supported MGK as he unveiled a ring collection The 8th Deadly Sin – GOSSIP with Stephen Webster at The Bomb Factory.

While they walked to the exhibition together, the couple did not pose for photographs together once inside the venue.

Megan added a boost to her height with black platform heels and carried a black shoulder bag in her arm.

Machine Gun Kelly, real name Colson Baker, 33, showed off his heavily tattooed torso as he went shirtless in a grey waistcoat.

He teamed the look with matching trousers and converses.

The couple made their first public appearance together since their reported breakdown of their relationship earlier this month at the Sports Illustrated Swimsuit launch.

It’s been rumored in recent months Megan’s engagement with MGK was on the rocks following allegations the rapper-turned-rocker had been unfaithful.

But they were spotted last month having reconciled on holiday in Hawaii.

A source said at the time that although they had endured a ‘rocky patch’ in their whirlwind romance, the couple  are ‘officially back on’ and ‘feel more connected than ever.’

But sources told PEOPLE Megan isn’t making it easy for MGK.

‘He’s doing whatever he can to get her back, and she’s making him work for it,’ an insider revealed.

‘They are slowly working on reconciling but he’s totally in the dog house still,’ added the source.

The couple’s inner circle are reportedly not placing their bets on success when it comes to the on-off couple making it to the alter.

‘It’s still an unhealthy dynamic though,’ said the insider, ‘and their friends just don’t see this lasting.’

The pair began dating in May 2020 following Megan’s shock split from her husband of 10-years and the father of her three children, Brian Austin Green. MGK proposed to the Transformers star the following January.

They met on Randall Emmett’s box office bomb, Midnight in the Switchgrass.

Megan declared at the time: ‘I knew right away that he was what I call a twin flame. Instead of a soul mate, a twin flame is actually where a soul has ascended into a high enough level that it can be split into two different bodies at the same time.

‘So we’re actually two halves of the same soul, I think.’
