Pregnant Rachel Riley looks radiant as she displays her blossoming bump in a multi-coloured summer dress while leaving Countdown filming

She's gearing up to welcome her second child. 

And Rachel Riley, 35, looked radiant as she stepped out in a multi-coloured dress after filming Countdown at Media City, Salford on Wednesday.

The mathematician's growing baby bump was showing under her summer dress as she headed home.

Rachel was all smiles as she strutted to her car in the bright stripped dress which she paired with brown sandals. 

The television personality completed her ensemble by carrying a colourful rucksack on her back.

She headed home to see her Strictly Come Dancing star husband Pasha Kovalev, 41, and their daughter Maven, 18 months.

Rachel recently spoke about her growing family in an exclusive interview with MailOnline.

She explained that she and Pasha felt unsure children were in their future during the early stages of their relationship, but after reflecting on her age and the possibility starting a family may not be easy, they decided to go full steam ahead.

'We've bashed them out! Get the sleep deprivation over in one go is the plan', she explained.

'I'm 35 and I've got friends that are struggling with fertility, and you just never know if you're going to be able to get pregnant.

'We have been really lucky, touch wood and we're very excited. They're great, we weren't sure if we wanted them before and we're just both in love, it's lovely.'

She continued: 'My first pregnancy was really mild and this one, you barely even notice it. Obviously, I'm chasing after a toddler the whole time, so it's a different experience.

'The first time you focus on the pregnancy and looking at yourself but the second time you know there's a baby coming.

'You're thinking about what the future is going to look like with your family of four, rather than focusing on your stomach looking different. It's an incredible thing the human body and I was lucky my giving birth experience was good.'
