Justin Bieber reportedly spent $75,000 in a strip club last night (20.01.14).

The 19-year-old singer flew from Colorado to Miami Beach for his friend Lil Scrappy's birthday party, first heading into Mansion nightclub before visiting the King of Diamonds Gentleman's Club a few hours later.

And a representative for the venue told website TMZ that once inside, the 'Baby' hitmaker changed up $75,000 into dollar bills and ''went wild''.

This isn't the first time the teenage star has visited a strip club.

In October, a dancer at a bar in Houston, Texas, revealed he had visited with boxer Floyd Mayweather.

Tweeting under the handle DiamondsR4Ever, she wrote: ''@justinbieber went The F*k In Tonight!!

''He Touched My Ass I Almost Fainted!

''He Was Like Its Real!!

I've Danced For A lot Of Celebrities And They Normally Don't Phase Me But Justin just Had Me In Shock! I am now a @justinbieber Fan (sic)''

The Canadian singer has sparked controversy for partying in over-21s nightclubs in recent months and the 'Beauty And A Beat' star's mother Pattie Mallette recently admitted she finds it ''difficult'' to let him make his own mistakes.

She said: ''When your kids hit a certain age your parenting style changes and it is hard letting go.

''His life was my life and now I've had to let him go a little bit and let him be independent. It is hard to not be able to control everything that your adult child does.''
