"It's not something that I feel 100 percent comfortable talking too much about, but just quickly, when I first found out about the news I kind of did want to throw the towel in," he said.

"But it was my mum who said to me that I've just got to keep going," he continued. "She told me very sternly that she wanted me to."

Tomlinson's mother died last December at age 43. Following her death, the 25-year-old singer performed his new single with DJ Steve Aoki, "Just Hold On," during a special appearance on the The X Factor U.K.

"It was tough, but I felt like it was nice for me to almost have a little send-off for her," he explained.

Tomlinson also opened up about his son, Freddie, who will be turning one on Saturday.

"I love him, obviously, but yeah, it's affected how I am as a person, a little bit," he said. Tomlinson shares custody of his son with his ex, Briana Jungwirth. "I'd like to say it's made me a bit more mature. I don't know if that's actually true."

When asked about former bandmate Zayn Malik and the type of relationship they currently have, Tomlinson responded, "It's a strange feeling but it's nice. I think a lot of us have spoken recently, me and Zayn have spoken recently, gotten to a point now where you can just really be happy for each other. Things have happened in the past, of course. It's great. His first song was an absolute smash and that's a great song."
