Kathy Hilton is celebrating her daughter’s happiness!

The mom-of-two, 64, spoke exclusively to PEOPLE at the Elizabeth Taylor Ball To End AIDS in Beverly Hills, Thursday and revealed that her daughter Paris Hilton is “over the moon” about being a mom.

“I've never seen my daughter happier in her life,” she says. “I've never seen her so happy.”

“Yes, and the three of them,” Hilton adds, referring to Paris, her husband Carter Reum and their son Phoenix Barron, whom they welcomed via surrogate in January. “She's always very upbeat and very even keel. She's never moody.”

Reum and Paris tied the knot in November 2021 at her late grandfather Barron Hilton’s former Bel Air home.

Elaborating further about her daughter’s parenting, Hilton tells PEOPLE that Paris asks her for advice on certain things, and also turns to sister Nicky Hilton for mommy tips. "You know, she'll call me for a certain advice or Nicky. I'm up there a lot," she says.

Nicky, 39, shares Lily-Grace Victoria, 7, and Theodora "Teddy" Marilyn, 5, and a son, 14 months — whose name has not been publicly revealed — with husband James Rothschild.

Hilton adds that Paris is “very gentle” and doesn’t get mad if she’s corrected about parenting. “Everybody needs to learn, right? It's not easy,” Hilton tells PEOPLE. “It's a lot. Even if you have somebody to help you it's a lot.”

She adds that Phoenix Barron, 8 months, recently had his first swimming lesson. "He's just so sweet and adorable," Hilton says.

During a March 2023 appearance on The Tonight Show Starring Jimmy Fallon, Paris opened up about her newborn. "He is such an angel, he's the best," she said. "I'm just so obsessed with him, I feel my heart is going to explode."
