Ed Sheeran and Cherry Seaborn announced the arrival of their daughter Lyra Antarctica Seaborn Sheeran on Instagram on Tuesday.
And an unearthed picture of Ed, 29, taken NINE months ago in Antarctica could explain the inspiration behind Lyra's unusual middle name and begs the question - is that where the baby was conceived?
In the photo posted by NotJust Clothing to Instagram on December 17, Ed posed on a boat surrounded by ice, although Cherry, 28, was not visible in the picture.

MailOnline has learned the clothing company sent Ed the festive jumper he is wearing shortly before he boarded his flight on the trip of a lifetime.
Eco-conscious Ed wore the 'David Attenbrrr' design, made from recycled plastic bottles while travelling around the icy continent.
And earlier, it was revealed Lyra's first name was inspired by the main character in her dad's favourite book series, His Dark Materials, by Philip Pullman.

Lyra Belacqua, also known as Lyra Silvertongue, is the heroine of Pullman's trilogy.
Lyra is a young girl who inhabits a parallel universe and finds herself embroiled in a cosmic war between Lord Asriel on the one side, and the first angel to come into being, called The Authority, and his Regent, called Metatron, on the other.
In 2015, Ed tweeted: '[By] far, Philip Pullman - his dark materials are the best books I've ever read.'
Ed announced the safe arrival of his first-born on Tuesday, sharing a picture of Lyra's booties and a colourful blanket.

Book store, Waterstone's write:

Revealing that Cherry had given birth the week before, he wrote: 'Ello! A quick message from me as I have some personal news that I wanted to share with you...
'Last week, with the help of an amazing delivery team, Cherry gave birth to our beautiful and healthy daughter - Lyra Antarctica Seaborn Sheeran.
'We are completely in love with her. Both mum and baby are doing amazing and we are on cloud nine over here.
'We hope that you can respect our privacy at this time. Lots of love and I’ll see you when it’s time to come back, Ed x.'
A source revealed the news that the couple were expecting last month.
They told The Sun: 'Ed and Cherry are over the moon. They’re very excited, but have kept things very low key.
'Lockdown was a perfect excuse not to be seen out and about too much, but things are getting closer and the excitement has been building so they have started telling friends and family.
'They’re just making the last of the preparations at home, and the baby is expected later this summer.
'It’s a really happy time and their families are all totally delighted for them and cannot wait to meet the new arrival.'
MailOnline contacted representatives for Ed Sheeran for comment at the time.
