Cat revealed she had already started her pelvic floor breathing exercises five days after giving birth.  

MailOnline has contacted both Cat and Jorginho's representatives for comment.

Shortly after Cat announced her pregnancy in March, it was reported that she was expecting her second child with Chelsea footballer Jorginho Frello, 28.

The singer is thought to have struck up a romance with Jorginho following the breakdown of his marriage to Natalia Leteri, reports the Sun.

Jorginho shares two children, Vitor and Alicia, with his estranged wife, who he is thought to have secretly separated from at some point last year.

The couple were together for eight years and tied the knot in 2017.

A source told the website: 'Cat fell hard for him and has struggled to keep their romance a secret. It became known to her circle of friends, the music industry and — through her role on The Voice — backstage on TV. 

'She told Jorginho she was pregnant just before her announcement. He was delighted and she's looking forward to becoming a mother for the second time.'

MailOnline contacted Cat and Jorginho for further comment at the time.

Cat told MailOnline earlier this year how her new relationship inspired her to write fresh material – almost five years after she became a mum to Ada, who she shares with the actor.

Singer-songwriter Cat said her daughter hopes to follow in her footsteps by competing in the next series of The Voice Kids and she believes Ada could go all the way as she can already 'stay in tune and hit high notes.'

Cat said: 'I definitely write a lot of love songs, especially last year. 

'I find I go through phases when I have inspiration and other times not but last year I entered into a new relationship and that definitely gave me loads of creativity and inspiration. 

'My songs are usually based on love – boring! It inspires me so much, there's no other feeling like it.'

Speaking about her daughter Ada, she said: 'She's already said she wants to go on The Voice Kids. 

'She's watched YouTube clips of the kids and asks if she's a better singer and I tell her she's amazing but say, 'She's probably had more practice than you, you really need to practice.
