Aston and Sarah welcomed their first child together in January 2018, and revealed in December that they were expecting their second. 

The parents met during a JLS tour when she worked as a backup dancer while Aston sang to crowds across the nation.

The couple announced their engagement on Boxing Day 2017, and subsequently admitted their wedding had been delayed due to work commitments. 

Their news comes just days after the couple shared an energetic dance TikTok video outside their home to Doja Cat’s hit Say So.

Sarah captioned the video: ‘Suns out bump out. 1 week til due date so we celebrate by dancing. Can’t believe how quick this pregnancy has gone, any day now we get to meet you little one.’ 

While Aston added: ‘Just one more week to go until and my baby really dancing like this at 39weeks. I think this could be the last one @sarahlourichards.’ 

Last month, the hunk ensured his fiancée got the baby shower she deserved as they prepared for the birth of their second child.  

Despite ongoing restrictions, the musician went out of his way to give Sarah a surprise by filling their living room with balloons and inviting close friends and family members to attend via video-link from their respective homes.

Speaking to OK!, Sarah admitted her pregnancy is something of an early Christmas present because neither of them had planned to extend their family.

‘It was a very pleasant surprise!’ she said. ‘I felt different for a week, and Aston was away filming. He came back at the end of the week and we took the test and it was a very clear, definite yes.’

She added: ‘I was quite shocked and it took me a minute to get my head around it because I just wasn’t expecting it.’
