The Project viewers stunned over Steve Price's 90-year-old mum: 'She looks younger than you'

Steve Price celebrated his 70th birthday with viewers of The Project on Monday.

However, the shock jock's celebrations were upstaged by his mother Margo.

Joining the studio audience to watch as The Project paid tribute to Steve's 15 years on the show, his proud mum looked decades younger than her 90 years.

'I think I speak for the entire nation Pricey when I say she looks younger than you,' his co-host Waleed Aly joked.

Price, who introduced viewers to his mother as '90 years young', looked teary after The Project showed a series of clips celebrating his decade and a half on Channel 10's panel show.   

During the segment, Margo paid her own tribute to her media veteran son, who has enjoyed a career spanning over four decades.

'He's a very generous person, different to what you see here on camera,' she said, before co-host Sarah Harris joked: 'So he wasn't grumpy as a toddler?' 

'No, no, always been wonderful,' Margo responded.

At one point in the segment Price thank the show's cast and crew.

'I want to say one serious thing about it – I've been here 15 years, and working with the young people on The Project, particularly behind the scenes, but also you three,' he said referring to his co-hosts. 

'And all of the ones that have come before you... But it makes me feel young, so I don't feel 70 at all, I feel about 55.'

Fans took to The Project's social media to wish Price a happy birthday, with many gushing his mother's appearance on the show.

'Happy birthday Steve Price!! Hope you’re enjoying your Special day. All the Best. Your Mum & you both look Great,' said one fan.

'I’m still getting over how AMAZING Steve’s mum looks!!!,' messaged another user.

'Omg his Mum!!!! Does not look her age!! Wow!' said another astonished viewer. 

Another fan added: 'Happy birthday Pricey. Agree with everyone, what a stunner his mum is!' 

It comes after The Project co-host Sarah Harris recently revealed why she doesn't wear G-string bikinis as she weighed into the debate around the revealing underwear during a segment on the show earlier this month.

The TV host, 43, gave her candid thoughts on the beachwear item 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 all happy for them to do it, I wish I was one of you, but alas,' 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 Blue Mountains City Council spokesperson there has been 'no change' to the council's policy regarding swimwear.
