Godsmack frontman Sully Erna wouldn't tell a radio DJ whether or not the band's song 'Cryin' Like a B---' is about his music rival Nikki Sixx of Motley Crue, but he sure dropped a big hint.

The two rockers have been butting heads since Erna complained about how the band was treated on the Crue Fest 2 tour. In fact, it was Sixx who said, "Every person — from road crew, fans and even all the bands on the tour [including Godsmack] -- was so happy, but [Erna] just seems to be crying like a b---."

Erna has admitted that the song was inspired by events that transpired on the Crue Fest 2 tour, without calling out Sixx by name. In a new interview with Q103 radio in Albany, N.Y., he doesn't answer the question directly but seems to suggest that Sixx is indeed the subject of the song.

When asked directly if the song is about Nikki Sixx, Erna says, "It's very difficult for me to restrain myself from answering that question because as honest as I'd like to be, the other side of me doesn't want to give anybody the extra exposure, even if it's negative. So, I'm just gonna plead the fifth."

Sixx also recently commented on the beef in a Twitter post. Click here to read more about what he said.
