The presenter, who co-hosts new reality show Last Choir Standing with Myleene Klass, said he thought it would be amusing to play a prank on the priest.

"The priest wafted it over the congregation and got everyone chilled out. It was a lovely service!"
Last Choir Standing kicks off tonight on BBC One.
