“We already miss him so much and feel the heavy weight of this loss. He was our best friend,” the relative wrote. “We love you more than you could ever know, Uncle Vic.”

In her emotional tribute to her uncle, she also added that the Alabama-native “loved his life” and that he “loved his work because it brought him so many of his friends.”

“A great comic. Loved doing radio with him but loved even more our friendship,” Hughes, 56, tweeted, sharing photos of himself with Henley, writing, “Always happy, rarely sad … never had a bad word to say about anyone. His laugh/giggle was so contagious which you wanted to be around.”

He added: “Just an incredible loss to his family, friends and the comedy community. The world is less loveable today. Thanks so.much for your friendship my brother.”
