Lady Gaga and Mick Jagger in bath

LADY GAGA had a chat to MICK JAGGER this week while soaking in her bathtub.

Thankfully for Mick he wasnt perched on her bidet during the conversation.

He was on the phone, after calling to discuss her collaboration with the ROLLING STONES during their gig in New Jersey this weekend.

A source said: Gaga didnt want to miss Micks call so she took it in the bath.

They spoke at length about whats going to happen.

She also asked Mick if she could wear any of his old stage gear for their performance.

Good luck fitting into his tight trousers.

Meanwhile, Mick made a rare TV appearance on Tuesday on David Lettermans US show.

He took part in a skit called Things I, Mick Jagger, Have Learned After 50 Years In Rock N Roll.

These included Be considerate of other hotel guests trash your room by 10pm and You dont earn a cent when someone does a song about having moves like Jagger.

Given how much that MAROON 5 track has raked in through airplay, Mick would be well within his rights to claim a few quid.
