Dustin Hoffman is mourning his late “Tootsie” co-star, Teri Garr.

“Teri was brilliant and singular in all she did, and had a heart of gold,” Hoffman, 87, told The Post on Tuesday. “Working with her was one of the great highs. There was no one like her.”

Garr died Tuesday morning in Los Angeles after a long battle with multiple sclerosis, her publicist, Heidi Schaeffer, confirmed to The Post.

The actress is survived by her daughter, Molly O’Neil, 30, and grandson, Tyryn, 6.

Garr played Hoffman’s friend and sometimes-love interest in the 1982 movie, “Tootsie.” She received an Oscar nomination for her work.

In addition to the Mike Nichols classic, the comedy legend was known for roles in Mel Brooks’ “Young Frankenstein.”

This is a developing story.
