The former couple welcomed son Bear in 2017 before splitting the following year after more than two years together.
Liam was asked about becoming a father for the first time during an interview on Logan Paul’s podcast Impaulsive.
“To be honest with you, it ruined a relationship at that point – but for all the right reasons,” he said of having Bear.
“I was so excited for him to be born that I was actually worried if I wouldn’t love him enough.”
Liam also opened up about Bear’s traumatic birth, saying: “[Cheryl] haemorrhaged quite badly giving birth so she was asleep for the first day. It was me and a baby in the room and I had to take care of it.”
He went on to call Cheryl the “best mum in the world”, adding: “I couldn’t ask for someone better. He is all she cares about and I couldn’t ask for more.”
Liam and Cheryl have both regularly spoken of how they have remained on great terms following the end of their relationship.
She told The Sun in 2019: “I’m actually really happy that we can be the way we are. We love and care about each other a lot and we share a child. It’s really important that we’re able to have a very healthy good relationship.”
She added: “We’re going to be in each other’s lives forever so we’ve got to figure it out and be grown-up about it.”
