Los Angeles, June 26 - 'Beautiful Girl' singer Sean Kingston says he regrets his decision to turn down a dance date with R&B singer Rihanna -- simply because he had no ironed clothes.

'Rihanna asked me to go clubbing with her. Looking back I can't believe I said no just because I didn't have any clothes ironed. But I couldn't go out with a superstar looking bad,' aceshowbiz.com quoted Kingston as saying.
