jay leno hospitalized

TV talk show host Jay Leno fell ill and checked himself into a Los Angeles, California, hospital Thursday, his representative said.

Leno was not taken to the hospital by ambulance -- he either drove himself or was driven by a staffer. NBC canceled Thursday's taping of "The Tonight Show with Jay Leno," after the talk show host became ill.

The network will rerun the March 26 show, which features a musical performance by Prince and interviews with actors Paul Giamatti and Emma Roberts, according to the show's Web site.

Actor Ryan Reynolds, animal trainer Jules Sylvester and swing band Big Bad Voodoo Daddy had been booked for Thursday's show.

A rep for Leno says he's still in the hospital for observation.

Tracy St. Pierre would not disclose the nature of Leno's illness.

Leno will be 59 on Tuesday.
