Sophie Turner subtly reveals daughter Willa's date of birth on a new necklace

Sophie Turner may have subtly revealed her baby's exact birth date.

The Game of Thrones star, who welcomed her first child, daughter Willa, with husband Joe Jonas a few months ago, has remained extremely private about her family.

However, in a new photo shared to her Instagram Story, the Game of Thrones star was seen wearing a beautiful gold necklace with a pendant that read "22.07.20."

"Thank you, @jenniferfisherjewelry," she wrote.

If the necklace is in fact her daughter Willa's date of birth, it will mean that she will be four months old in a weeks time.

Turner and Jonas are yet to debut a photo of the newborn, but the family of three have been spotted a number of times walking in Los Angeles, with Willa in a pram. They were photographed in public for the first time last month.

Amid the coronavirus pandemic, the pair were wearing facemasks while their daughter was concealed in the pram behind a blanket.

"Joe and Sophie have been very cautious about who is around them and their little girl," a source told Entertainment Tonight at the time.

Turner and Jonas tied the knot in May 2019 after three years of dating. They reportedly welcomed their first child together in July, following their very private pregnancy.
