What's more, on Sunday, Leigh-Anne hinted just how close she was to giving birth, writing: "I have dreamt of the moment I get to meet you, hold you, guide you, teach you. It’s nearly time 🖤"
Perrie announced the arrival of her little one, whom she shares with English professional footballer Alex Oxlade-Chamberlain, just yesterday via Instagram, without yet revealing the baby’s name or sex.
Sharing two close-up, black-and-white photos, the 28-year-old wrote: "Welcome to the world baby 21/08/21 ♥️."
The post was soon flooded with support, including from Leigh-Anne herself who penned: "I am so proud of you and I love you so much 🥺 what an angel ❤️❤️😍😍."
Fellow Little Mix member Jade Thirlwall also sent her love, writing: "😭♥️ Proud of you always. Ly ✨."
Noticeably absent from the public well wishes was Perrie's former band member Jesy Nelson who left Little Mix in December, 2020.
However, the singer did get a message of support from her ex-boyfriend's bandmate's sister. Yep, that's right, Lottie Tomlinson (sister to One Direction's Louis Tomlinson) penned a sweet, "😍 Congratulations ❤️".

Perrie was famously previously engaged to former One Direction member Zayn Malik who now shares a child, Khai, with model Gigi Hadid.
Zayn and Perrie's relationship ended on rocky terms, with the latter eluding to the fact she was dumped over text. But now, both parties seemed to have moved on and started their own families.
As for Leigh-Anne, we guess we'll just have to wait and see when she actually announces the arrival of her first child. If Little Mix fans are right, it may just be six days from now 👀.
