The mystery behind the sex of Kate Middleton's child might have been revealed, again, by a gift given to Prince Charles.

The soon to be grandfather was given a mini dark blue racing outfit while visiting the Williams' Formula 1 racing team in Doha, Qatar, according to The Huffington Post.

But the baby sex was supposedly revealed after Middleton received a teddy bear from a young girl when she visited the National Fishing Heritage in Grimsy earlier in March.

When accepting the gift, she said "Thank you, I'll take that for my d-," then cut herself off.

However, the baby's sex hasn't yet been confirmed. And the website for the Formula 1 team is also blue.

The Huffington Post joked that the gift could be a sign that Middleton's baby would become groomed to be a racer by his or her grandfather. The Australian Grand Prix will take place from March 15 through the 17 in Melbourne. Williams' FW35 2013 racecar was launched on Feb. 19 in Spain.

The Duchess of Cambridge has also been on a new workout routine because of her pregnancy. According to Hollywood Life, she started doing yoga instead of running and has been reading baby books.
