Heidi Montag goes TOPLESS in sizzling photoshoot to promote her new pop single Wet Hot Summer - as she hits back at 'mom shamers' for slamming her sexy look

Heidi Montag is baring all for one of her raciest shoots ever - and hitting back at the 'mom shamers' who have slammed her for stripping down. 

The 37-year-old donned a pink G-string and posed topless in a jacuzzi for the photoshoot, which is to promote her new single, Wet Hot Summer. 

In images shared exclusively with DailyMail.com, the mom-of-two posed in a soaking wet T-shirt that clung to her chest, before ditching the top completely.

The blonde bombshell covered her cleavage with her hands and delivered a series of smoldering looks to the camera. 

In other photos, she showcased her toned abs and gym-sculpted curves as she posed up a storm in the hot tub.

The Hills alum has already received backlash for the racy photos, with one troll writing, 'You're a mom of two boys - stop this!'

'So much for the "Christian" Heidi,' another barked, while one snapped, 'She does literally anything for attention.'

Heidi and husband Spencer Pratt share sons Gunner, 6, and Ryker, 18 months, together.

Responding to the backlash, Heidi told DailyMail.com, 'I thought we were beyond this point in the culture of being so critical and shaming moms and women for being more than one thing.'

She continued, 'I'm just following in the footsteps of incredible women like Jennifer Lopez, Beyoncé and Katy Perry who show you can be a mom and still be sexy.

'Why is that as soon as women have kids they get solely defined by that, but men are never defined by fatherhood? Chris Hemsworth and Jason Momoa get praised every time they take their shirts off, but God forbid a mom wears a bikini!'

The reality star admitted that she felt like she'd been singled out more than others over the years - especially when it came to her appearance. 

'People have always felt like they could say whatever they want about me and get away with it,' Heidi, who once went under the knife for 10 cosmetic surgery procedures in a single day, said.

'The things that were said about my surgeries back then were so cruel that you would get canceled if you said it now.

'I don't know why I've always been a target but I've learned to ignore it and focus on the positives because I get so much support from my fans so there's really no need to look at the haters.'

The I'll Do It hitmaker is now focused on her music career and has plans to release her long-awaited sophomore album this year. 

She released her debut album Superficial in 2010, which flopped at the time after it only sold 1,000 copies in its first week. 

However, the record has gone on to earn a cult following among pop fans and has gone viral on TikTok in recent years thanks to her breakout hit I'll Do It, earning Heidi more than one million monthly listeners on Spotify. 

'I'm just so excited to have so much support for my music."I'll Do It" has been trending everywhere and Superficial is a pop culture phenomenon now,' she gushed.

'I thought my music dreams were over but thanks to everyone supporting the songs I'm able to step back into this music career that I've always wanted and I can show everybody that it's never too late to chase your dreams,' Heidi continued.

'I've obviously been focused on being a mom for a while and that is always my number-one priority, but now it's such a fun time for me to do some things for myself again.' 

When asked about the sound of her new album, Heidi promised that it was going to live up to the hype. 

'It's definitely the sophomore album that everyone has been asking for. It's another classic, it might be ahead of its time like Superficial was but overall I think it's where it needs to be,' she explained. 

'The music is still in that pop lane, but there's also some edgier songs and really sexy stuff too for everybody that loved "I'll Do It." 

'It just has something for everybody and I'm excited to get back out there!'

Wet Hot Summer will be released on all streaming platforms on June 28.
