The Project host Sarah Harris shocks co-stars with wild 'wee' confession

Sarah Harris stunned The Project viewers on Tuesday night when she made a shocking 'wee' confession.

The TV presenter, 43, left her co-hosts wide-eyed when she revealed she has urinated in the South Bank public Boat Pool in Brisbane. 

She admitted that 'everyone wees' at the pool, which is a large lagoon open to the public, before appalling her colleagues when she confessed to doing it herself. 

Her admission came during a segment about American musician FINNEAS who recently said he didn't understand why Brisbanites seemingly 'hated' South Bank. 

Comedian Kate Langbroek suggested the locals' disdain may be because of the rumour that the famous South Bank Boat Pool is 'full of urine'. 

'Everyone wees at South Bank,' Sarah quickly cut in. 'I've weed at South Bank.'

Fellow hosts Sam Taunton and Waleed Aly were stunned by the sudden confession, while Kate, 59, attempted to brush it off.

'It's a massive body of water. It's like saying, "People wee in the ocean." It's a victimless crime,' Kate said. 

However, Sam was still reeling over Sarah's bathroom habits, as he said: 'Can we just go back? You weed in the pool at South Bank?'

'Yeah. It was a long time ago,' Sarah responded defensively. 

The shocking admission comes after Sarah revealed why she doesn't wear G-string bikinis as she weighed in on the debate about the revealing frock.

The TV host gave her candid thoughts on the beachwear item on The Project recently while discussing a ban on them that has been issued by a list of swimming pools.

Blue Mountains Leisure Centres (BMLC), an arm of the Blue Mountains City Council, sparked backlash by declaring that G-strings are 'not acceptable' at its facilities.

Weighing in on the controversial move, Sarah insisted she has no problem with people wearing thong bikinis but revealed why she won't be wearing one herself.

She quipped: 'I wish I could wear them! My bum looks like a garbage bag filled with cottage cheese! I think if you've got it, flaunt it.'

Sarah—who shares two sons Paul, seven, and Harry, five, with her ex-husband Tom Ward—also hit back at critics who claim that G-string bikinis are not family friendly.

'A lot of the comments have been, "What will the kids think?" I spend a lot of time at the beach with my kids, they're not looking,' she added.

Her co-host Georgie Tunny agreed with her sentiments as she shared her bewilderment over people's opposition to thong swimwear.

'I just don't care, I don't care what people are wearing, if they feel confident enough to wear that then I'm happy for them to do it, I wish I was one of you,' she said.

G-string swimwear was banned at Katoomba Sports and Aquatic Centre, Springwood Aquatic and Fitness Centre, Blackheath Pool and Glenbrook Swim Centre in the Blue Mountains.

The BMLC's terms of entry state that 'patrons are encouraged to shower thoroughly before entering the pool and recognised swim wear must be worn'.

'Recognised swimwear does not include G-strings,' the conditions add.

The council was forced to explain what it meant after swimmers noticed a sign that ruled 'revealing swimwear/thongs' were banned, which prompted some backlash.

The council then clarified online: 'The image of "Revealing Swimwear/Thongs" has raised some eyebrows, this image refers to thongs and G-strings not bikini tops and bottoms.

'Bikinis are acceptable and considered recognised swimwear.'

A number of locals were perplexed by the ban of the popular style of swimwear and it prompted some divisive backlash.

'Shouldn't people go to the pool to SWIM and not to worry about what other people are wearing,' one said.

'How about we solve this by placing the responsibility with the person having feelings about somebody else's clothes and not the kids wearing them,' a second local said.

'Young people will wear what's fashionable and these are what are fashionable. If you don't like it, don't look.'

A third urged others to 'stop worrying or commenting about how other people look or what they are wearing'.

'If someone is so offended by a cheeky G-string bikini, then don't wear one and don't look at others wearing them,' they wrote.

'There's lots of bodies at the pool that I don't enjoy looking at, they still have every right to be there and wear what they want.

'This policy is so old fashioned and outdated in my opinion.'

But others said they didn't see an issue with the ban, adding that there is still swimwear they can wear at the pool.

'I don't see the problem here. People are taking this out of context. It's not like they're saying cover everything up,' a user wrote.

'There are so many kids who innocently swim and enjoy, only to see many sets of butt cheeks walking by which I actually find ridiculous,' another said.

A Blue Mountains City Council spokesperson there has been 'no change' to the council's policy regarding swimwear.
