Sian Welby has revealed she was 'forced to urinate in the middle of the A3' after being trapped in horrendous traffic at the weekend.

The TV and radio star, who is 37 weeks pregnant, went to the toilet on the side of the road after sitting in four hour traffic on the motorway with little to no movement.

Speaking on Tuesday's edition of This Morning, Sian said she rushed towards the bushes for cover but there were 'brambles everywhere' and she had to wee in the middle of the road instead.

She said: 'I had to do a wee in the middle of the road, into the bush and I didn't dare go in there as it was full of brambles and nettles'.

The person she was travelling with captured the hilarious moment on camera, with Sian darting to try and find some privacy so she could wee.

Presenters Dermot O’Leary, Josie Gibson and Giles Brandreth broke out into laughter at the scenes, with Giles saying: 'Is this you coming back from your wee? Now I've seen it all. Morning television isn't what it used to be, is it?'

Dermot added: 'The mystique is definitely gone, but who doesn't love a pee-pee rustique from time to time?'

This prompted Sian to admit: 'Do you know what? It was exhilarating.'

Sian kept her followers up-to-date with the horrendous traffic on social media which took almost five hours to clear. 

As the traffic started to move, the pregnant star filmed the 'reported roadworks' which hadn't even occurred – with a row of traffic cones causing the chaos that brought the motorway to a standstill.

It comes after Sian admitted she is finding giving up alcohol 'so much harder than I ever expected' during her pregnancy.

Last month, Sian jetted off to Tenerife with fiancé Jake for a holiday and while sharing an insight into their trip on Instagram, she uploaded a photo of Jake enjoying a glass of white wine.

She captioned the post: 'Not drinking on this holiday is so much harder than I ever expected'.

The NHS recommends if you're pregnant or planning to become pregnant you should not drink alcohol.

Drinking in pregnancy can lead to long-term harm to the baby, with the more you drink, the greater the risk.

The Captial Breakfast presenter announced she is expecting her first child with her fiancé Jake Beckett back in February, and that she is due to give birth in June. 

Sian said at the time: 'I think I want to share something with the group right now, actually. 

'Seriously, guys: got a bit of an announcement for you. I'm pregnant! I don't know how I've managed to keep it from you for this long, but I am, it's not a joke.'

Sian became engaged to Heart Radio producer Jake during a romantic holiday to Greece in 2023.
