John Legend's model fiancee Chrissy Teigen has set a 2013 deadline for her impending wedding after continually having to postpone potential dates.

The R&B star proposed to Teigen in December, 2011, and a representative for the couple was recently forced to dismiss reports suggesting they were planning a winter wedding in North Carolina for January (13).

Teigen previously expressed interest in having a spring or summer (13) ceremony, but she admits they have still yet to decide on when to tie the knot - although she is determined to pull it off by the end of the year (13).

She tells the New York Daily News, "We keep pushing the date... Definitely this year, but this year just started", and she jokes, "If it's not this year, I'm out!"

And Teigen, who has been dating Legend for seven years, admits she's growing tired of people quizzing her about their wedding.

She says, "We were sick of people saying, 'When are you getting engaged?' - so we did. And now everyone's asking when we're getting married."
