Kelly Osbourne has offered her friend Miley Cyrus some advice following the former child star's controversial MTV Video Music Awards on Sunday (25Aug13). Cyrus has been all over the headlines after taking the stage with Robin Thicke for a sexually-charged duet on his hit song Blurred Lines, and many people in Hollywood have criticised the 20 year old for going too far with her raunchy routine, but Osbourne has offered up some more pointed advice. She says, "Look Miley's my friend and I love her, and I have her back no matter what, but, as her friend, I'm going to tell her - put your f**king tongue in your mouth! I love you, but just put your tongue in your mouth." Previously, Osbourne defended her pal on Twitter.com, telling followers, "I wish ppl (people) would back off @MileyCyrus... yes she pushed peoples buttons but she is young & expressing herself... I think people forget that she is an actress! She only played #HannahMontana but she IS @MileyCyrus!"
