Los Angeles: Singer Lady Gaga holds Mick Jagger in high regard and so when the Rolling Stones star called her she attended the call despite being in the shower.
Jagger, 69, called to discuss Gaga`s collaboration with his band Rolling Stones in a New York gig.
"Gaga didn`t want to miss Mick`s call so she took it in the bath. They spoke at length about what`s going to happen," thesun.co.uk quoted a source as saying.
Known for her bizarre dressing, Gaga even "asked Mick if she could wear any of his old stage gear for their performance," the source added.
