Kid Rock is not what you'd call a big fan of Justin Bieber.
He spoke out about the star on Howard Stern's radio show on Wednesday, likening Bieber to Vanilla Ice, and predicting his long, hard fall from grace.
Or whatever you'd call where Justin is right now.
Rock was promoting his $20 Best Night Ever tour, where he's charging fans only $20 a ticket, when the topic of Bieber's recent woes came up.
"Tell me if this is wrong," he asked Howard. "Justin Bieber ... is 100 percent like watching Vanilla Ice all over again. It's exactly the same."
When Stern remarked that Ice was a one-hit wonder, Rock amusingly responded, "Well, then as soon as Bieber has a hit, he'll be like Vanilla Ice."
