Back in November 2005 GMTV presenter Jenni Falconer joined the cast of West End musical Chicago for a one-off performance with Darius.
She took the role of murderess Roxie Hart opposite Darius's smooth-talking lawyer Billy Flynn.
The pair performed the number We Both Reached For The Gun, in which Flynn acts the ventriloquist with Roxie as his dummy.
Jenni said at the time: "Performing the routine was great fun but absolutely exhausting both physically and mentally - as I had no prior stage dance experience I found it very difficult to learn the routine and had to have several rehearsals before I was even half-way ready to do it for the cameras.
"Still, I was in the very enviable position of sitting on Darius's knee!"
