Get ready for a royally big dose of cuteness!
Spencer Matthews and his wife Vogue Williams have shared their first photos of their son Theodore, who they welcomed to the world on September 5 this year.
"What's up guys!! I'm Theodore and daddy thinks I look the cutest in my mouse hoodie," Pippa Middleton's brother-in-law captioned his Instagram picture.
Proud mum Vogue also took to social media to show off her adorable son her many followers.
"Look at that smile....Theodore you are my world 💙💙💙," the TV presenter and model captioned her snap of Theodore, dressed in knitted overalls.
In September, the couple gave us our first look at baby Theodore in an exclusive magazine spread with British magazine HELLO!.
They also revealed that his middle names are a tribute to two late family members - Vogue's father Frederick and Spencer's brother Michael, who died aged 22 in 1999, after reaching the summit of Mount Everest.
"His name lives on in our family and always will do," the Made In Chelsea star told the magazine.
Spencer's brother James Matthews and his wife Pippa Middleton are due to expect their little one any day now. In fact, Pippa's sister Duchess Catherine is even rumoured to be skipping out on Princess Eugenie's royal wedding day which is around her due date.
Speaking to OK! Online, Alex Apati of Ladbrokes said, "The early betting suggests Pippa will follow in Kate's footsteps by choosing a traditional name for her first-born."
"There's been plenty of speculation, but punters are torn right now over the gender, although the head of the baby name market is dominated by male names."
We are loving the sentimental sweet name that Spencer and Vogue decided on, but not all celebrities have followed suit this year.
