Paris Hilton, 43, makes the rare move of taking her son Phoenix, one, out during errand run in LA as she models a You Are Beautiful T-shirt

Paris Hilton was casual and kept a low profile while running errands with her one-year-old son Phoenix in Los Angeles on Monday.

The 43-year-old socialite — who recently gave influencer Alix Earle some advice on how to continue “sliving” (killing and living your best life) — opted for a gray sweatshirt that read, “You are beautiful.”

She paired the look with black sweatpants and Nike tennis shoes while carrying her baby in her arms.

The reality star pushed a stroller while wearing a navy blue Yankees cap and Prada sunglasses.

Her blonde locks were tied back in mini buns and she bared her face sans makeup during the outing.

Hilton’s eldest son received a lot of attention late last year when numerous Instagram users left comments on her posts making fun of the size of his head.

The entrepreneur has spoken People last November and told the media that her “mama bear instincts” surfaced after reading several comments about her son.

The model lashed out at the users who commented about Phoenix, describing those who did so as “cruel” and “miserable.”

“I couldn’t believe they could be mean and nasty about a little innocent baby,” she added.
