John Legend says his fiancée is ''always right''.

The 'Ordinary People' soul star is set to wed model Chrissie Teigen in September and claims the key to wedded bliss rests with his agreeing with his future spouse's opinion.

He said: ''Even if she's wrong, she's right. That goes for anything. I'm getting married soon and to be fair, she listens to me, but she's always right!''

The 34-year-old star is hard at work planning his wedding but one thing which will definitely happen is he will serenade Chrissie, 27, at the reception.

He added to Q magazine: ''The wedding won't be small but not too large, it's mostly family. I just have a big family. Am I playing? I'll probably do a song or two. Do I take requests? No. I'm not into wedding bands.''

The piano-playing singer feels that he and glamorous Chrissie complement each other because they both have a passion for fashion, and he believes it's important to dress well to attract the ladies.

He explained: ''Dressing well is knowing what looks good on you. A good fit is important. Just don't be douchey. I was in Cannes [France] the other day and was laughing at these guys who had these pop-collar polos with writing on the back of the collar. They looked douchey! You don't want to look like you're trying too hard.''
