British rap star Just Jack was so starstruck when Kylie Minogue called to ask him to collaborate on a song - he fell off his chair.
The Starz In Their Eyes hitmaker admits he was shocked that Minogue called him personally to re-record his album track, I Talk Too Much, for his American release record, Overtones.
He says, "I fell off my chair. It was a shock.
"Before she arrived at the studio, we were wondering how we should react and how we should behave. It was like waiting for the Queen. "
