Preview: Olly Murs gets waxed!

No celebrity is safe... That's right, Ant and Dec (and their amazing pranks) are back for a brand new series this week!

Watch our preview above as Olly Murs attends Madame Tussauds for what he thinks is a very ordinary measuring up for his waxwork figure... Turns out Ant and Dec have plans to make this anything but ordinary...

Expect a system malfunction, lots of yellow gunge and a very wet Olly.

You can see even more in our photo gallery of Olly at Madame Tussauds here!
