Splittsville?

Aerosmith frontman Steven Tyler and longtime fiancee Erin Brady may be saying "no more, no more" to their relationship, according to the New York Post.

Aerosmith frontman Steven Tyler and longtime fiancee Erin Brady may be saying "no more, no more" to their relationship, according to the New York Post.

A source tells the paper that the two are on the verge of a split because Tyler is looking to devote all of his time to re-energizing the band, which is ready to hit the road, and staying sober. The insider says that the much-younger Brady is "kind of a Yoko Ono character" who is making that difficult, adding “The tour is really important to him and the band. So he decided to end it.”

Tyler's rep denies that he's single again, insisting Steven and Erin are asking for their privacy at this time, adding, "They are engaged to be married and each is committed to their sobriety. Any claim to the contrary is absolutely false and misleading.”
