Courtney Love and Dave Grohl buried the hatchet after bonding over "an actress' boobs".
The Hole frontwoman had been embroiled in a feud with her late husband Kurt Cobain's former Nirvana bandmate since the rocker's death in 1994 and though they appeared on good terms when the group were inducted into the Rock and Roll Hall of Fame in April, Courtney admits it took a recent conversation to really become friends again.
She explained: "A lot of people saw the Rock and Roll Hall of Fame where we hugged it out and it was all good, but the other night we - we used to really like each other and then there was 20 years when we sued each other and then we stopped - and then the other night we just started talking about this one actress' boobs.
"We'd both seen them - at one point, when she was 20 they were the sexiest boobs in Hollywood - he'd seen them, I'd seen them, and we just picked up where we left off after 20 years of suing each other.
"Me and Grohl, we're totally tight!"
And the 'Malibu' singer went on to claim her repaired friendship with the Foo Fighters star is proof anyone can resolve their differences.
Speaking on US talk show Jimmy Kimmel Live, she said: "We're totally tight. If you can give up a grudge like that -- because there was a lot of c**p that went on -- I think anyone can do it."
However, Courtney insisted being friends with the 'Walk' star doesn't mean she will make music with him.
She said: "I think we have a bit of a different demographic."
