Speaking after the announcement, she told the magazine: “We had a miscarriage last year and so there was a part of me that was afraid to tell about this baby too soon because I was so afraid something would happen again and I that didn’t want. gotta tell the world a little bit’.

She further revealed that the couple found out they were expecting a baby while traveling with her family to Australia.

Roxy explained, “It was really lovely because I have to tell my mom pretty much straight away and I don’t see my parents too often, so it was a really perfect time before he went on tour.

“We found out the same week that my grandmother had passed away. There’s a part of me that feels like my grandma knew we were trying for a baby and maybe this was her gift to us.

Jack has been dating Roxy for over two years and they live with their dog Coco in a £17.5 million five bedroom house in Notting Hill.

It comes shortly after Jack admitted he was insecure about his life path after losing some friends in “rehab” while his other friends have had children.

He talked about his relationship with his girlfriend Roxy when he shared that they bought a house together.

He explained that while he is now “settled” with Roxy, he is still unsure about his future plans as he hinted that he has not yet decided if he wants children.

Appearing on Capital Breakfast with Roman Kemp, Jack said he has lost friends through “rehab” and having “babies” while talking about his own life path.

Speaking to deputy host Will Manning, he explained, “I’ve settled in, I’ve got a long-term partner, I’ve bought a house with her, we’ve got a dog and do all those things. .

‘I don’t want to say it [my tour] I am furious against the dying of the light [laughs] but it gives me a sense of this man child… getting through this moment in my life, losing half my friends to rehab, half my friends to babies and trying to figure out which way to go.”
