Paris Hilton is hitting the recording studio with her baby boy Phoenix.

The mother of two, 42, shared a cute TikTok video that featured her son, who turns 1 on Tuesday, enjoying himself in the studio as she recorded her second album.

“Are you a happy boy?,” Hilton asked as Phoenix bounced on his seat in a gray onesie. “Do you like watching mommy in the studio?”

“Dancing, dancing, dancing, dancing,” Hilton then sang as her son began to laugh and nod. “Yeah, dancing. Go, go, go, dancing.”

“At the studio recording my 2nd album with Baby P,” the entrepreneur’s caption read. “Which artists would you like me to do a song with? #SlivingMom.”

“You can tell he is so loved. So precious,” one person commented.

“His smile when he looks at you says ‘I love you mommy,’ ” a second added, while another wrote, “Oh Paris, these videos always catch me off guard on my FYP and just melt me.”

Back in October, Hilton opened up about her star-studded new album during an appearance on The Tonight Show Starring Jimmy Fallon.

“I’m doing my new album, and Sia is executive producing it,” she revealed to host Fallon, 49.

“Wait, the Sia?” asked Fallon.

“The Sia,” replied Hilton.

The record will be a follow up to Hilton’s 2006 debut album, Paris, which featured her hit single “Stars Are Blind.”

In addition to Phoenix, Hilton shares daughter London Marilyn, 9 weeks, with husband Carter Reum, and often shares snaps of her two children.

Earlier this month, Hilton shared a TikTok video of London having some tummy time.

“My little bunny🥹🐇 So in love with my baby girl London💕👶🏼💕,” her caption read as the baby girl moved her legs while laying on her stomach in a pink bunny onesie.

Hilton also shared an edited version of a previous TikTok where Phoenix was captured dancing to “Last Christmas” by Wham! In the following TikTok, the video was edited so Phoenix appeared to be dancing to Hilton’s single with Steve Aoki, “Lighter,” as the background color flashed and changed.

“#Sliving runs in the family🥳 #MiniSliver 👶🏼,” her caption read, while the caption on the screen added, “When you realize that clubitis is hereditary and your mom is Paris Hilton.”
