Howard Stern Show” regular Johnny Fratto has died after a battle with lung cancer, TMZ reports. He was 61.

Fratto was reportedly with his wife Ivanka and other family members at the time of his death on Thursday.

Fratto appeared regularly on “The Howard Stern Show” and was a close friend of Eric “The Actor” Lynch, one of Stern’s most memorable guests and a member of the host’s “Wack Pack,” who died last September at age 39.

Stern paid tribute to Fratto via Twitter on Thursday afternoon.

Fratto also owned the Beverly Hills Choppers motorcycle and bike company. His father was the late Louis Thomas Fratto, who had ties to the Midwest mob in Chicago, Illinois and Iowa from the 1930s until his death in 1967.

He is survived by his wife and son, actor Johnny Fratto Jr.
