Megan Fox posed for a sizzling shoot this week – and revealed her surprising insecurity over wearing her hair up.

The actress, 36, looked incredible as she modelled a stylish half-updo with strands framing her face, paired with a busty, flesh-flashing ensemble.

The star showed off her flawless make-up and bone structure in the snap – but admitted the hairstyle was a new departure for her.

Wow: Megan Fox posed for a sizzling shoot this week – and revealed her surprising insecurity over wearing her hair up

She wrote: ‘I never wear my hair up because my head is the size of a tiny edamame bean but this happened and we’re all okay. Baby steps.’

The beauty wowed in a feather adorned top, which plunged to reveal her ample cleavage.

This was paired with a glittering sheer skirt which revealed her toned legs as she stood on the bed.

Last month Megan celebrated her 36th birthday with fiancé Machine Gun Kelly at a star-studded bash hosted at Tao, Las Vegas.

Her usual look: Megan usually opts for flowing tresses down her shoulders

The Jennifer’s Body actress put her ample cleavage on display in a glittering sleeveless gold dress and donned a silver crown for the special occasion.

Earlier in the day, the star and her other half, 32, made an appearance at the the 2022 Billboard Music Awards, where MGK sparked pregnancy and marriage rumors after he referred to Megan as his ‘wife’ and dedicated his song to their ‘unborn child.’

Others celebrities partying with Megan were Mary J Blige, Usher, Heidi Klum, Lil Kim, Jermaine Dupri, Teyana Taylor, French Montana, Anitta, Shensea, Nelly, Ray J, City Girls, Trey Songz, Bryson Tiller and more.

While on the red carpet at the Billboards, the pair discussed Megan’s birthday, with MGK saying, ‘It’s my fiancée’s birthday at midnight so we are celebrating her wonderful night.’

However Megan’s reply suggested that MGK would be doing most of the partying, as she stated: ‘I’m boring I don’t drink, but I’m sure he’ll go off for me.’

The dynamic duo – who have been engaged since January of 2020 – made waves at the music show when MGK said ‘I wrote this song for my wife,’ during his performance of Twin Flame.

Halfway through the performance, he added, ‘This is for our unborn child’ sparking rumors that the two were expecting their first child together.

Following the eyebrow-raising comments, an insider told E! News: ‘People in the audience turned to each other perplexed and said, “Wife?”‘

Both of them are already parents. Megan is a mom to sons Journey River, five, Bodhi Ransom, eight, and Noah Shannon, nine.

Her children’s father and former spouse Brian Austin Green, 48, is currently expecting another baby with girlfriend Sharna Burgess, 36.

Meanwhile MGK is a dad to 12-year-old daughter Casie, with ex-girlfriend Emma Cannon.

Fox has not confirmed whether or not she is expecting, but did not show any sign of a baby bump on the red carpet in her cleavage-baring black gown.
