The Mendez family remembered Juan Carlos at a memorial earlier this week.
Eva Mendes' older brother sadly lost his battle to throat cancer.
Juan Carlos Mendez was diagnosed with cancer a year and a half ago and died on April 17 at the age of 53. The Mendez family celebrated the father of two's life on Tuesday at the Church of the Recessional in Glendale, California.
Eva's younger brother, Carlo, remembered Juan Carlos as a "funny charming genius comedian creative hot tempered crazy calm person" in a touching Instagram post.
"I have no idea how to cope with him being gone but I want to thank you all who have reached out to me and believe me when I say your messages make me feel a little bit better. My life will never be the same without him. Thank you all," Carlo wrote.

The 2 Fast 2 Furious actress has shared her own sweet posts about her brother, including a throwback photo of Juan Carlos alongside which she wrote, "Sending him so much love today as he continues his battle with cancer. I love you big brother."
Earlier this month, she shared a photo of them together and captioned it simply with a heart.
When Carlo announced the tragic news, he said that Juan Carlos passed "peacefully." "He fought with all his might and power and gave cancer one hell of a fight. He leaves behind a 13-year-old and a 5-year-old," Carlos wrote. "I love you my brother may god bless you and I'll see you once again."
