Rapper Wiz Khalifa has been taking financial advice from property tycoon Donald Trump's money managers in a bid to get his business affairs in order.

The Black and Yellow hitmaker recently filed suit against concert promoters It's My Party, Inc. over an axed gig in Washington, D.C. and he suggests the legal action was prompted by talks with associates of the billionaire mogul.

He tells Esquire magazine, "Right now, I'm learning to sue people and get my money. After talking to people who work for Donald Trump - smart, successful people - I've realised I gotta go after all that. That's what I'm going to do that I didn't last year."

The concert lawsuit isn't the only court battle Khalifa is involved in - last year (12) he was named as a defendant in a copyright infringement complaint filed by songwriter Max Gregory Warren over allegations the hip-hop star's 2010 hit Black and Yellow plagiarised a song he wrote in 2007, Pink N Yellow.
