The figure, which displays a scantily-clad Minaj, was made based on the rapper’s music video for “Anaconda”.
One visitor posed with her tongue about to lick the figure’s derriere, reports aceshowbiz.com.
“Madame Tussauds attractions are interactive, immersive experiences, and our visitors are generally respectful towards the wax figures,” the museum said in a statement.
“It is unfortunate that this visitor decided to behave so inappropriately and we apologize for any offense this has caused,” the statement added.
The museum is also tightening security around the figure.
“We do have staff monitoring guest behavior in the attraction and do our utmost to ensure our wax figures are treated respectfully, but on this occasion clearly one of of our hosts was not present,” the statement continued.
