Lady Gaga, who keeps a personal record of her life on the road as a memento to hand down to her children in years to come, wants to publish them. "As she tours the world, Gaga notes everything down in her journal,” a source told the Daily Star. "It contains her thoughts, feelings, sketches, pictures and even letters between herself and mum Cynthia.

"She keeps it all together as a memento, so that if she ever has children they'll be able to read all about their pop star mum.

"Gaga also says that one day she would consider allowing it to be published, if the timing was right."

But the eccentric singer wouldn''t be using the diary to cash in.

We're told: "She often talks about how funny it would be to publish it. But if she did, her decision wouldn't be based on money, it would be for the fans.

"Gaga would consider it to be a gift to them,” the source added.
