Megan Fox and Machine Gun Kelly put on a united display as they step out in London

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

The couple showed unity as they dismissed speculation about their on-off relationship.

Megan, 37, turned heads when she went braless in a form-fitting white crop top and high-waisted black trousers with a silver diamond necklace.

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

While walking to the exhibit together, once inside the venue the pair didn’t pose for photos together.

Megan boosted her height with black platform shoes 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 gray vest.

He paired the look with matching pants and conversation pieces.

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

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

But they were spotted last month after reconciling on vacation in Hawaii.

A source said at the time that although they had weathered a “rocky patch” in their whirlwind romance, the pair are “officially back” and “feeling more connected than ever.”

But sources told PEOPLE Megan doesn’t make it easy for MGK.

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

“They are slowly working on reconciliation but he is still completely in the dog house,” the source added.

The couple’s inner circle is reportedly not betting on success when it comes to the on-off couple making it to the altar.

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

The couple started dating in May 2020 after Megan split from her husband of 10 years and the father of her three children, Brian Austin Green. MGK proposed to the Transformers star in January.

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

Megan stated at the time, “I knew right away he was what I call a twin flame. Rather than a soul mate, a twin flame is actually where a soul has ascended to a level high enough to be split into two different bodies at the same time.

“So we’re actually two halves of the same soul, I guess.”
