Miley Cyrus' former TV mum Brooke Shields has taken aim at the pop star for her provocative performance at the MTV Video Music Awards on Sunday night (25Aug13), insisting the grown-up Hannah Montana star looked "desperate" onstage. Shields played Miley's mum on the hit Disney show and her daughters, aged six and 10, are big fans - but the actress wasn't impressed with her ex-co-star's saucy routine at the Barclays Center in New York. The 20 year old stripped down to her rubber underwear and donned a giant foam hand to perform Blurred Lines with Robin Thicke, who seemed more than a little bemused as his stage partner danced provocatively in front of him and grinded her backside into his crotch, while making inappropriate gestures to the audience. Shields was a co-host on U.S. breakfast show Today on Monday (26Aug13) and admitted she didn't like what she saw. She joked, "I don't approve. What did I do wrong?" Shields then got serious, adding, "I just want to know who is advising her and why it's necessary (to do that). My six year old and my 10 year old, they can't watch that. "She can sing beautifully, and I feel like if she lets that lead, rather than let her bottom lead… I feel it's a bit desperate - you're trying to be (Lady) Gaga... but it's different... She's trying so, so hard." But Shields gave her one-time TV daughter top marks for grabbing the headlines: "She went for it... and we're all talking about her." The actress wasn't the only famous mum stunned by Miley's moves - Thicke's mother, singer Gloria Loring, was also confused by what the former child star was trying to achieve. She says, "I don't understand what Miley Cyrus is trying to do. I think she's misbegotten in this attempt of hers. And I think it was not beneficial. I didn't get what her point was. It was so over the top as to almost be a parody of itself."
