Malibu, California - Paris Hilton is the proud mother of a baby girl!

The 42-year-old shared the sweet news with her 25.5 million followers on Instagram. The picture she posted shows pink pajamas with the word "London" on them, red heart-shaped sunglasses, and a cuddly stuffed bunny.

"Thankful for my baby girl," Paris wrote, revealing the gender and name of the child.

Back in January of this year, Paris announced that her son Phoenix had been born via a surrogate. The heiress had expressed the desire to have another child, and was hoping for a girl.

It is not known whether her daughter was also born with the help of a surrogate or was adopted. The blonde beauty previously said she had her eggs frozen together with her husband, Carter Reum, whom she wed in November 2021.

Paris Hilton's name choice comes as no surprise. She told Ellen DeGeneres last year that she definitely wanted to call her daughter London Marilyn.

She also admitted that she would like to have two or even three children. It remains to be seen whether baby number three will follow soon.

Many celebrities took to Instagram to congratulate the mom of two, including supermodel Naomi Campbell (53), who wrote: "Congratulations @parishilton & welcome London."

Actors Bella Thorne (26) and Dakota Fanning (29) also chimed in with well-wishes.
