Paris Hilton’s brother Barron and wife Tessa welcome a baby girl named Milou Alizée Hilton

It’s a girl!

Paris and Nicky Hilton’s younger brother Barron, 30, welcomed his first child with wife Tessa von Walderdorff and the couple announced the good news on Instagram Friday.

Barron and Tessa posted a sweet snap from the hospital cradling baby Milou Alizée Hilton who was born earlier in the week.

‘Welcome to the world our baby girl! Milou Alizée Hilton 03.11.2020,’ Tessa captioned her Instagram snap.

The selfie shows 26-year-old Tessa in her hospital gown cozied up with her husband and holding her new baby in a bundle of blankets. 

Looking away from the camera, Barron sweetly stares down at this first child in the image.

Nicky Hilton took to social media to express her joy over being a first time aunt with a snap of herself with her sister-in-law back when she was pregnant. 

Barron and Tessa announced that they were expecting their first baby together back in the fall. 

‘We’re having a baby!!!!!!!!!!!!! This feels like an absolute dream!’ the soon-to-be mom captioned an image of herself kissing Barron.

‘I cannot even begin to express how much love and adoration I have for this man. And to think that we are now creating a beautiful little miracle between the two of us simply blows my mind,’ she continued.

‘We already have so much love for you baby and we cannot wait to welcome you in our arms with hugs, kisses and smiles. This is the most precious gift of all. Our whole world is glowing!’ 

Their pregnancy news came just over a year after they tied the knot during a lavish ceremony attended by his parents, Richard and Kathy Hilton, and his socialite sisters, Paris and Nicky.

‘The couple is radiating with joy,’ their rep told People.

Barron and Tessa conceived the baby this summer in St Barths, the same place where they met three years ago and where they go married in June 2018. 

The baby will be Richard and Kathy’s third grandchild, as his sister Nicky already has two daughters with her husband James Rothschild.

Barron proposed to Tessa in October 2017, calling her the girl of his dreams when he announced the news of their engagement on Instagram.

Less than a year later, they said ‘I do’ in St Barths.
