Courtney Love aimed a bizarre rant at Katy Perry during a gig in New York City this week (beg09Sep13), branding the pop star "boring" and urging her to be more like Miley Cyrus.

The Hole star performed during a book launch at the Dream Downtown hotel in Manhattan on Monday (09Sep13), and during her set she took aim at the I Kissed a Girl hitmaker.

Love told the crowd she is a fan of former child star Cyrus, who has been shocking critics with her raunchy performances in recent weeks, but insists Perry doesn't take enough risks.

She says, "I liked Miley, frankly. I'm gonna be honest, Katy Perry bores the (f**k) out of me. She's a nice girl, she just really bores me. You know, that hillbilly Miley Cyrus is sort of punk in a weird sex way..."

Love went on to take aim at another pop star Robin Thicke, as well as actor/rocker Jared Leto, adding, "Can someone inform me who Alan Thicke's son is? Like what? Wasn't (he on) Charles in Charge (sitcom)? That's like Jared Leto trying to convince me he's a rock star."

She later added to New York Post gossip column Page Six, "(Perry) bores me. (Miley) was at least kind of punk rock, you know? It was openly sexual... like dark and hillbilly and (f**ked) up."
