Security has been stepped up around Nicki Minaj's wax model.

The 32-year-old beauty was immortalised as the character from her 'Anaconda' music video but a series of inappropriate photographs taken with the statue at Madame Tussauds in Las Vegas has caused a headache for the company.

In a statement, they said: ''We have been made aware of the inappropriate photograph that was taken at Madame Tussauds Las Vegas, involving Nicki Minaj's new wax figure ... It is unfortunate that this visitor decided to behave so inappropriately and we apologise for any offence this has caused. We do have staff monitoring guest behaviour in the attraction and do our utmost to ensure our wax figures are treated respectfully, but on this occasion clearly one of our hosts was not present.

''We are taking immediate steps to ensure more staff are present in this area and that the set around this particular figure is redesigned so that a picture like this cannot be taken again.''

However, Nicki didn't seem bothered by the photographs after she uploaded one to Instagram, captioning it: ''Naw bitch hold on. (sic)''
