Megan Fox has “mooned” fans to celebrate being in “a fourth house Taurus sun”.

The ‘Transformers’ actress, 37, who has said she believes she and her fiancée Machine Gun Kelly are parts of a “twin flame”, peeled down to a see-through dress and bared her nipples and bum in a creek-side photoshoot, which she shared as her latest Instagram post.

She captioned the carousel of flesh-flashing images: “A fourth house Taurus sun.”

Astrology sites say about the term: “With your Sun in the 4th House, your identity is likely to be formed or influenced by the level of emotional support you receive from others.”

It’s not known if Megan was referring to her recent relationship troubles.

But it appears her romance with MGK, 33, is back on track as she recently covered up the tattoo on her pelvis dedicated to her ex-husband Brian Austin Green.

She first revealed the inking – which read ‘Brian’ in dramatic lettering – eight years ago before they split in 2020, and her tattoo artist has now shown off how she has had a snake and flowers etched over his name.

Her tattooist – who goes by the name Jesse Tattoo on Instagram – posted a raunchy image of the new design showing Megan pulling up her top and showing off the top of her privates.

He captioned the image: “Coverup tattoo for @meganfox. Was able to completely hide the old tattoo underneath the new snake and flowers she wanted… very grateful for all of the opportunity tattooing has given me and all of the cool people I’ve met along the way (peace sign emoji.)

“Thanks for your trust @meganfox.”

Mum-of-three Megan has three sons – Noah, 10, Bodhi, nine, and six-year-old Journey – with Brian, and their divorce was finalised in 2022.

It’s understood the former are still on good terms as they co-parent their kids.

Megan has also used tattoos to pay tribute to MGK, and showed off a collarbone design that reads ‘El pistolero’ – Spanish for “the shooter” – in an obvious reference to her rapper partner’s stage name.

The on-again couple got engaged in January last year and are seemingly back together after a dramatic split earlier this year.

They also share matching voodoo doll tattoos on their ring fingers.

The couple even tattooed each other during a GQ shoot, with matching designs that read ‘The darkest fairytale’.

Megan told the magazine the phrase “alludes back to one of the first text messages we ever sent each other”.
