The couple – who kept their pregnancy news secret for some time – shared their happy news this evening, alongside a video of their daughter.
They wrote: “And then there were 3…She’s here and she’s perfect.”
Sonny and Danielle’s famous friends rushed to comment on it, with Perrie Edwards writing: “Omg 🥹 Congratulations gorgeous! Enjoy every second of that perfect baby bubble.”
Olly Murs commented: “Awww huge congratulations.”
Shelby Tribble said: “Oooooh this is so exciting congratulations”, while Pixie Lott added: “Yayayaya congratulations!!!!”
The pair announced they were expecting at the start of this year as they revealed Danielle’s bump for the first time.
Danielle and Sonny, who won Dancing On Ice in 2021, revealed they were in relationship last summer.
The news came a year after Sonny split from music producer Lauren Faith, who he proposed to in 2020.
Influencer Danielle previously dated One Direction star Liam Payne for two-years until 2012.
A decade later they rekindled their romance again for a brief time over the summer in 2022.
Sharing her romance with Sonny last year, Danielle gushed: “After years of mistreatment, I learned that the reason I’d accepted so little from guys is because I hadn’t put in the work on myself to discover my boundaries, find my confidence and also know my worth.
“Without even realising that I’d evolved, I met Sonny, and I didn’t even need to express my morals, standards or desires in a relationship. He just gets it. He gets me, and I’ve never felt safety in a relationship like this.
“So much so, that I feel proud to share a private segment of my life with my online community, something I haven’t done for years, if ever in this way.”
