Madonna says Adam Yauch, the Beastie Boys rapper who died Friday, was one of a kind and that the group was important to her musical history.

The singer says the seminal hip-hop group was "integral to the musical revolution that was happening at the time."

Yauch’s representatives confirmed that the rapper, also known as MCA, died Friday morning in New York after a nearly three-year battle with cancer.

Madonna says she was sad to hear of Yauch’s death and asked God to bless his family. The Beastie Boys opened for Madonna on tour in the 1980s, and the group was inducted into the Rock and Roll Hall of Fame last month.Cole loves Rihanna’s don’t-care attitude

Cheryl Cole is a huge fan of Rihanna and admires the ‘Umbrella’ hitmaker’s ‘I-don’t-give-a-damn’ attitude.

The Girls Aloud singer- who has previously claimed that the 24-year-old is her "girl crush" - admires the ‘We Found Love’ singer, as she is the "perfect pop star" due to her carefree attitude.

"You know what I love about Rihanna? I know she gets a lot of criticism, too, about what she wears and what she sings about, but she is so free," Contactmusic quoted her as telling GQ magazine.

"She doesn’t give two f**ks. I love that in her. I love that sense of freedom about her. She’s gorgeous and free. A perfect pop star," she said. She also likes Rihanna’s liberal attitude to life, and believes the pair have had similar experiences in their past relating to their partners.

"She’s been through the same thing absolutely. And you can imagine how intense it is when all the world’s eyes are on you. So she knows that feeling. But she’s free-spirited, she just doesn’t give a s**t," Cole said.

"Maybe it’s going through everything she’s gone through that has enabled her to get to that point. She’s like, ‘Whatever. What more can you say about us? You can’t hurt us any more.’ I love that about her. It’s liberating. She’s liberal," she added.
