Megan Fox, Machine Gun Kelly keeping alive their hot-cold romance, spotted in London

Machine Gun Kelly and Megan Fox have just arrived in London.

On Tuesday night, the couple was seen together attending an event in London after a source previously told People magazine that they are trying to "make their relationship better."

The 37-year-old actress wore white see-through asymmetrical tank and studded black trousers with a matching clutch and platform shoes, showcasing her newly dyed ginger hair.

The 33-year-old musician flaunted his tattooed arms while wearing an oversized, sleeveless grey suit. He finished off the ensemble with a lengthy necklace that hung down and black and white trainers.

Last week, a source told the outlet of the couple, "They are back together. They have explored therapy. Things are still not back to normal though."

The couple was engaged to each other since January 2022.

The source added that Fox and MGK "were wedding planning, but not anymore. They don't have a wedding date. Megan still seems hesitant."

"She has just put so much time into their relationship. It's hard for her to let go," said the source.

The Jennifer’s Body actress teased her potential break up with longtime beau in this past February, when she removed all photos of her with musician fiancé from her social media and posting a cryptic caption. Soon after a week, the actress returned to Instagram to finally say a word on viral speculations of her relationship might be over,

Fox wrote at the time, "There has been no third party interference in this relationship of any kind. That includes, but is not limited to...actual humans, DMs, AI bots or succubus demons."
