Steph Claire Smith shows off her growing baby bump in a skimpy bikini as she hits back at trolls

Steph Claire Smith has taken to social media to flaunt her baby bump in a cheeky film clip.

In the footage, the 30-year-old podcaster can be seen wearing a skimpy bikini while miming the lyrics to Lily Allen’s 2009 hit, F*** You.

Captioning the clip, ‘Mum’s Should Cover Up’, Steph appears to be clapping back at body shaming trolls.

‘I’ll do me, you do you,’ Steph told her 1.5million followers in a message she shared in the post.

In the clip, the ultra-fit social media star, wearing a baseball cap and sunglasses, can be seen performing a series of hip-shaking moves as she lip-syncs to Allen’s protest song. 

Steph can be seen miming to the chorus which includes the lyrics: ‘F*** you (F*** you), f*** you very, very much.

‘Cause we hate what you do, And we hate your whole crew, So, please don’t stay in touch.’

The song was originally written as a protest against ultra-conservative bigots who hold to homophobic and racist views.

Steph’s post appeared to meet a positive reaction from her followers.

‘Yesss!! Our children deserve parents who celebrate themselves and their bodies (especially mumma’s!) in all stages of our lives,’ messaged one fan.

‘Bloody good on you girl! I’d be in a bikini too if I looked like you!’ said another.

‘If I looked as good as Steph I would never wear anything other than a bikini,’ added another user.

It comes after Steph, who shares son Harvey, two, with husband Josh Miller, claimed she lost Instagram followers after announcing she has attention deficit hyperactivity disorder [ADHD]. 

The fitness influencer revealed on Stellar’s Something To Talk About podcast she noticed a ‘massive spike’ in unfollows the day she revealed her ADHD diagnosis.

‘There was a massive spike in unfollows and I looked at the date and it was the day I had posted about my ADHD diagnosis,’ she said.

Steph, who is expecting her second child with husband Josh Miller, said women were previously ‘misdiagnosed’, with more people now learning they have ADHD.

‘It’s a horrible sentiment online with ADHD over the last couple of years because a lot of people are coming out with this diagnosis,’ she continued.

‘People think it is this trend and they’re sick of hearing about it so I was very aware of that and it was one of the things that made me very nervous about sharing it.’

Steph bravely spoke about her health update in a vulnerable confession in October and admitted she felt ‘relieved’ when a doctor confirmed her diagnosis.

Speaking on KICPOD, the podcast she co-hosts with fellow influencer and business partner Laura Henshaw, Steph said she first prompted to be tested after inviting Em Rusciano on the show to discuss her experience with ADHD.

‘Just the other week, I was diagnosed with ADHD combined,’ she said on the podcast.

‘I had Em on, and she spoke about her later ADHD diagnosis, and during the conversation, there was just so much that I didn’t realise, but I was nodding along and agreeing with and relating to her story.

‘At one point, she said that I might be a little bit neuro-spicy, which at the time, I was like, “I don’t know.”‘

The model and mother-of-one went on to detail the screening process she underwent for a woman in her 30s and confessed she was worried about not receiving a diagnosis.

Attention Deficit Hyperactivity Disorder affects about one in 20 Australians.

It’s characterised by persistent patterns of inattentive, impulsive and sometimes hyperactive behaviour, and is frequently accompanied by emotional regulation challenges, according to ADHD Australia.

While ADHD is the most common disorder among boys four to 11, the Australian Institute of Health and Welfare says about half the number of girls the same age are diagnosed.

That’s not because girls don’t have ADHD, experts say, but because they usually have the inattentive type of the condition which means their symptoms can fly under the radar.
