Meg Ryan was America’s sweetheart and John Mellencamp was the rock star everyone loved, but their relationship ended on such a bad note that the singer dropped the bombshell that she hates him “to death.”

Mellencamp, 65, told Howard Stern on his Sirius XM radio show that he and the You’ve Got Mail star did NOT get along.

“I love Meg Ryan and she hates me to death,” the "Jack and Diane" singer announced.
