US reality star Paris Hilton and her husband Carter Reum recently welcomed a son via surrogacy.

The hotel heiress confirmed this to the US magazine “People” on Tuesday (local time).

"We are so excited to start our family together and our hearts are exploding with love for our baby boy," the 41-year-old told the magazine.

It was not known exactly when the baby was born.

On her Instagram account, Hilton posted a photo of a baby's hand clutching her thumb.

"You are loved beyond words already," Hilton wrote in a blue-hearted post.

In addition to many well-wishers in the comment column for the post, stars like Heidi Klum and Kim Kardashian were also happy with the new mother.

In the recent past, Hilton herself had repeatedly discussed her desire to have children with partner Reum.

In December, she explained that she had egg collection during the pandemic lockdown.

Hilton and Reum got married in November 2021.

Surrogacy, in which another woman carries a couple's biological child to term, is illegal in Germany for ethical reasons.
