Bono wrote a character reference for Courtney Love so she could move into her new apartment.
The Hole singer - who moved out of her New York townhouse last month despite winning a long-running legal battle with her former landlord - is now living in a rented condominium in the Nolita district of Manhattan, thanks to a glowing report from the U2 frontman.
She told the New York Daily News newspaper: ''They didn't even credit-check. They chose Bono [from my character references]. And he wrote me a paragraph.''
And Courtney - widow of Nirvana frontman Kurt Cobain - says she will keeping the noise down at her new home after finding out one of the neighbours was pregnant.
She said: 'It's all good now. I didn't know! I don't do noise complaints.''
In January, a court case against Courtney claiming she owes back rent on her New York home was dropped.
The mother-of-one had been renting a $27,000-a-month townhouse on West 10th Street for 11 months, and while owner Donna Lyon had alleged in court that she owes $54,000 in rent, Judge Jean Schneider of New York County Housing Court threw out the claim.
Judge Schneider ruled that Ms. Lyon had improperly relied on outdated lease provisions.
Courtney's lawyer, Eric Sherman, said: ''We are pleased with the court's decision. The judge decided there was no non in the nonpayment. She has always paid her rent on time, in fact sometimes in advance of when it was due.''
