Reports surfaced yesterday that eternally young-ish Aerosmith frontman Steven Tyler was contemplating leaving the band because his bandmates -- sniff -- "don't appreciate him." According to one of those shifty-eyed anonymous sources we all love so much, Tyler's daughter Liv was overheard saying that her pops was fixin' to split due to his unfair treatment. Not so, counters Liv's rep Steven Huvane. (We knew Joe Perry was a gentle soul!) Huvane told the Post, "Liv never said anything about her father leaving Aerosmith." So boo-yaa.
