John Legend's fiancée has joked they have too many guests for their wedding.

The 'Ordinary People' hitmaker is preparing to marry Sports Illustrated model Chrissy Teigen, 27, in early September near Lake Como in Italy and they have been busy preparing for the big day.

The invites have been sent but it seems the couple are too popular and aren't getting any drop outs, meaning their guest list is swelling up.

Chrissy told the New York Post newspaper: ''We just sent the invites out. We're getting way too many back.''

The bride-to-be is planning to wear a custom-made Vera Wang wedding dress and will be having her final fitting this weekend to make sure it clings to all the right places.

The pair, who got engaged in 2011 after four years of dating, have hired a wedding planner to organise their nuptials and are excited to share the special day with their friends and family.

She previously said: ''I'm excited. I can't wait for the ceremony. [John] and I have been working and travelling so much that we just let our wedding planner do everything. We're not neurotic about it. I just want to finally see all of my friends in one area.''
