James Middleton and Alizee Thevenet's Relationship Timeline

James Middleton (Kate Middleton's younger brother) and French financial analyst Alizee Thevenet are parents!

After announcing their pregnancy in July 2023, the couple welcomed a baby boy, Inigo, in October 2023.

Middleton credits his late dog Ella with introducing him to his wife. Ella happened to walk up to Thevenet and brought the two together. Since that fateful first meeting, Middleton and Thevenet have taken trips, weathered a pandemic that brought several wedding postponements and welcomed many more pets to their family — including a litter of puppies, sheep and even a hive of bees!

From their sentimental wedding in 2021 to welcoming their first child, here's everything to know about James Middleton and Alizee Thevenet's relationship.

Rather embarrassed, I went over to apologize and bring Ella back."

Thevenet thought Middleton was a server and ordered a drink while petting the dog.

"Little did I know, I had just met my future wife, all thanks to Ella," he shared. "If I hadn't trusted Ella, I wouldn't have brought her to the South Kensington Club and she wouldn't have been able to say hi to the woman who became my fiancée."
