Donald Trump has been endorsed by some key political players in the days leading up to the Iowa caucus, and on Monday he added another big name to his celebrity roster - Kid Rock.

The rocker and rapper, who identifies as a libertarian, said in an interview with Rolling Stone that he was backing The Donald in the upcoming election, telling the magazine that his 'campaign has been entertaining as s***.'

He also said of Trump's qualifications; 'My feeling: let the motherf***ing business guy run it like a f***ing business.'

Reasons: The singer said in an interview; 'My feeling: let the motherf***ing business guy run it like a f***ing business' (Trump and wife Melania in Iowa on Monday above)

Kid Rock said of his decision to support Trump; 'I'm digging Trump. I feel like a lot of people, whether you're a Democrat or a Republican, feel like if you get Hillary or Bernie, or you get Rubio or Cruz or whoever, there's going to be the same sh*t.'

He then added; 'Let the business guy in there. It's not really working too well running it not like a business. I mean, what business f***ing survives when they're f***ing broke?'

Kid Rock also said that he expects Trump to win the Republican nomination.

This is not the first time Kid Rock - who was born Robert James Ritchie - has gotten political, having also endorses Mitt Romney in his failed 2012 bid for president against Barack Obama.

The musician even went to rallies in the days leading up to the election to perform in support of Romney and his running mate Paul Ryan.

He was also recently in the news for his use of the Confederate flag over the years, especially after the fatal shooting of nine people at a black church in Charleston, South Carolina this past June.

In response to a protest over his use of the flag, Kid Rock said in a statement to Fox News' Megyn Kelly; 'Please tell the people who are protesting to kiss my a**.'

Trump meanwhile is not feeling the love from another artist who, though not American, is far, far more influential than almost everyone in the music industry - Adele.

A spokesman for the singer released a statement on Monday saying that the British superstar did not give permission for Trump, or any other candidates, to use her music after learning he had been playing her 2012 hit Rolling in the Deep at rallies over the past few months.
