Beyoncé Knowles says she strives to be like her friend Gwyneth Paltrow.

The 29-year-old superstar shared her enthusiasm for the Oscar winning actress and spoke of why she likes being around her so much.

In a new interview with Harper's Bazaar UK, the Single Ladies singer says she even has trouble sometimes pulling herself away from Gwyneth.

'She pushes her boundaries all the time,' Beyoncé gushed. 'You go to her house and she makes you feel like you never want to go home. She is what I strive to be one day.'

But it seems like the feeling is mutual and Gwyneth told the magazine that she is enamoured with Beyoncé.

'She is what it means to be a superstar. No one else can sing and dance like that, while having humour and genuine bursting sweetness. She has her own recipe for it,' Gwyneth enthused.

' wanted my own character [in Country Song], to have some of hat mega-wattage. So I studied B. She was my homework.'

Beyoncé and Gwyneth's other halves, Chris Martin and Jay-Z are also great friends and the Iron Man star said they all get on so well because there is no ulterior motive.

'We have very similar values,' Gwyneth says of the foursome. 'We have also been able to become each other's support systems over the years, as none of us needs anything from the other.'

Beyonc2 turns 30 on September 4 and she revealed the big milestone means a lot to her.

'This is such a pivotal moment in my life! I'm transitioning as a woman, and I'm finally able to express myself as I am,' she surmised.
