Cheryl said getting pregnant was given his first chance to relax since the beginning of his career.
“I haven’t stopped in 14 years,” she said ITV’s Lorraine show, describing his life as a “roller coaster”.
The former Girls aloud singer marked the end of his free time in strutting on the runway at Paris Fashion Week earlier this month.
It was also recently revealed that she would be returning to the X Factor as a guest judge to Simon Cowell’s house.
The pregnancy has given her time free, she added in an interview with Cowell, which has been shared with The Sun.
The singer, 34, announced the birth of his first child with One Direction star Liam Payne in March, later revealing that they had named the Bear.
His artistic career started on Popstars: The Rivals in 2002, where she became part of Girls aloud alongside Kimberley Walsh, Nicola Roberts, Sarah Harding and Nadine Coyle.
She has launched a solo career before they disbanded, and went on to become a judge of X Factor in 2008.
“When I got pregnant, I thought,” good, I don’t need this stress”, so I am relaxed,” she said.
But despite the break from work, she “hated being pregnant”, she said. “A lot of things went on and I just don’t enjoy it.”
The maternity leave is “perfect” and allowed him to “reset the mind-frame”.
“I really feel better come back, I feel more relaxed. I just feel like I’m sitting in my own skin. I feel so good.”
She will now join the show’s boss, Simon Cowell, at his home in Nice, France, invited by the X Factor judge to help refine the participants for the ITV programme.

She first met Payne in 2008 when he auditioned as a solo candidate for X Factor, two years before the Direction formed on the show.
Asked how they decided on the name for their child, which would have taken weeks to decide, Cheryl joked that the Bear stood for “unbearable”.
She said having a child “changes your life completely, but in the most amazing way”.
“But I had the best six months of my life. Really.
“You know, a lot of mothers have to rush to work and I don’t think it is really fair so I’m going to take the time, a few more months, until it is a little bit higher,” she said.
