Barron Hilton is overjoyed about his sister Paris’s new addition to the family.

In a recent interview with the People at his mother Kathy Hilton’s DirecTV Xmas event on Tuesday, the 34-year-old billionaire stated that the arrival of the socialite’s baby girl, London, had left him speechless.

Last week, Hilton announced the birth of her second child, a baby girl named London.

Barron stated that the news caused a surge of happiness in the family, adding that none of the family members expected it coming.

Paris, he says, is looking forward to playing ‘dress up’ with her newborn girl. He added that he has a ‘small cache’ of outfits for the new baby.

On Thanksgiving, Paris didn’t hide her feelings; she was quick to share photos of her ‘dream’ family, which included her 10-month-old son, Phoenix Barron, and her husband, Carter Reum.

Meanwhile, Barron and Tessa are about to become parents for the third time, with their third child due in March.

The couple has kept the gender a secret and is not yet ready to discuss it.

“We’ll be outnumbered,” Tessa told the outlet, adding, “The memories. I mean, it’s hard now to imagine even when it’s just Barron, Milou and myself on the beach and Caspian’s napping we’re like, there’s something missing.”

“So it just keeps growing and it just keeps getting fuller. And the memories just keep getting better,” she went on to remark.
