The two musicians were both in attendance to honor Nirvana's induction into the Hall of Fame. Love is deceased Nirvana frontman Kurt Cobain's widow, and Grohl served as Nirvana's drummer and was Cobain's longtime friend.
Love and Grohl have never enjoyed a particularly close friendship, and their relationship became more acrimonious after Cobain's 1994 suicide. Their present-day interactions have been largely legal in nature, with an occasional public insult or accusation thrown in.
The pair appeared to put their differences aside last night when Love embraced Grohl onstage at the ceremony.
"This is my family I'm looking at right now," Love said. "I just wish Kurt could have been here. Tonight he would have really appreciated it."
She later posted a picture of the hug on her Facebook and Twitter and wrote, "The most magical part of the evening. Thank you Dave, love you. I know this made him smile up there." She also wrote a separate tweet addressed to Nirvana bassist Krist Novoselic that included the hashtags "hatchetburied" and "deepintheground."
