The Jennifer’s Body star took to Instagram to announce the news

Megan Fox has announced that she’s pregnant with her fourth child.

The star took to Instagram on Monday, November 11, to share her baby joy.

In one photo, the mom-of-three showcased a blossoming baby bump, while a second photo saw a positive pregnancy test.

She captioned the snaps: “Nothing is ever really lost. Welcome back.”

Fox, 38, tagged her partner Machine Gun Kelly (MGK) in the photo. It will be the couple’s first child together.

Prior to dating Machine Gun Kelly, 34, Fox had been married to fellow actor Brian Austin Green for ten years.

Over the course of the relationship, they welcomed three kids: Noah, Bodhi, and Journey.

Meanwhile, rapper MGK shares teenage daughter Casie with his ex, Emma Cannon.

UNILAD have approached both Fox and MGK’s reps for comment on the couple’s happy news.

The celebrity pair’s baby joy comes after Jennifer’s Body star Fox debuted a baby bump in MGK’s music video for his single ‘Lonely Road’ that was released over the summer.

Fans were quick to question if they were expecting their first child together, and took to social media to share their thoughts.

One Twitter user said at the time: “IS MEGAN FOX ACTUALLY PREGNANT OR WAS IT JUST FOR THE VIDEO?!???”

A second penned: “WHAT DO YOU MEAN THAT MEGAN FOX IS PREGNANT?!?!?”

Last year, Fox sadly suffered a miscarriage, which she revealed in her poetry book.

She later shared more on the heartbreaking ordeal in an interview with Good Morning America.

“I had never been through anything like that before in my life,” the actress said of her pregnancy loss.

“I have three kids. So, it was very difficult for both of us. And it sent us on a very wild journey together and separately, and together and apart, and together and apart, and together and apart, trying to navigate, ‘What does this mean? And why did this happen?'”

Fox’s relationship with MGK remains unclear, as the pair called off their engagement earlier this year.

She did describe the rapper as her ‘twin soul’, however.

The Transformers favorite said on the Call Me Daddy podcast: “I think that what I’ve learned from being in this relationship is that it’s not for public consumption, so I think as of now, I don’t have a comment on like the status of the relationship per say.

“What I can say is that is what I refer to as being my twin soul and there will always be a tether to him no matter what. I can’t say for sure what the capacity will be, but I will always be connected to him somehow.”
