"The greatest thing in life is seeing my daughter go from strength to strength. We're so excited to be expanding the family. It's the best blessing ever."
Dressed in a black ensemble with her long red hair flowing in waves, fans couldn't get over how much she was channelling her on-screen character Sansa Stark.
There has been speculation that Sophie also took inspiration for her first daughter's name from the show, as several characters named Willa appear across the eight seasons.
Meanwhile the George R. R. Martin book series the show was based on features another character with the name, albeit with a different spelling: Wylla Manderly.
Perhaps Sophie and Joe will choose another GOT-inspired name for their second child?
The proud new parents wed back in May 2019 in a surprise Las Vegas ceremony, following it up with a bigger event held in France the following month.
While fans are hoping for a glimpse of the pair's new bub, it's unlikely they'll be seeing her any time soon.

Sophie and Joe are notoriously private with their children and choose to keep Willa off social media entirely.
It's likely they'll continue the trend with their second daughter, meaning it's unlikely we'll be seeing any baby snaps soon.
In the meantime, fans are waiting patiently to find out what name they chose for their new bundle of joy.
