Katie Holmes must have been going through Suri withdrawal during a dinner celebrating the premiere of her film “The Son of No One” at the Sundance Film Festival.

The actress/mom played with castmate Simone Joy Jones’ 3-month-old brother at the event, held at Park City, Utah's Silver, a witness told us.

“She was very cute with him,” the spy said.

Holmes sat with co-stars including Ray Liotta and Channing Tatum, who sipped Vida tequila with wife Jenna Dewan throughout the night.
