Rocker STEVEN TYLER's daughter MIA has defended her dad's decision to quit  AEROSMITH, and told his ex-bandmates to stop gossiping about the singer's departure online.

Tyler's former songwriting partner Joe Perry and ex-bandmate Brad Whitford have both taken to Twitter.com to chat about the shock news, and guitarist Perry also took to the airwaves in Michigan on Monday to chat about the band's future and slam the singer.

But Mia Tyler wants the pair to shut up and just get on with their lives.

In a Twitter.com post, Tyler's daughter writes, "They (Aerosmith) are in their 60s now. Let them do what they wanna do! & can someone please tell (them) that gossiping on Twitter is uncalled (for)!"
