Paying tribute to Darlene Cates, actor Leonardo DiCaprio says she was the "best acting mom" he ever had.

The Oscar winning actor Leo shared silver screen with Cates in 1993 drama What’s Eating Gilbert Grape, and received his first ever Academy Awards nomination for supporting role.

Leo, who is also a climate change activist, wrote on Facebook: “Darlene was the best acting mom I ever had the privilege of working alongside”.

Cates passed away on March 26 during her sleep at her home in Texas. Her daughter Sheri confirmed the news of the death on social media. She was 69.

"Her (Darlene) endearing personality and incredible talent will live on in the memories of those who knew her, and those who loved her work,” the Revenant actor said

“My thoughts and prayers are with her family during this difficult time.” Leonardo added.
