The Hills stars Heidi Montag and Spencer Pratt have called time on their marriage - they have decided against making their union official.

The reality TV couple jetted off to Mexico last month to tie the knot in secret and were due to make their marriage legal with a legitimate ceremony at the Beverly Hills courthouse in Los Angeles.

But the pair opted out of the wedding at the last minute, in footage filmed for the hit TV series.

Pratt was seen telling his partner, "I just want to give you the wedding of your dreams that you have been talking about for three years. I'll deal with it. It's worth it to be with you the rest of my life. We'll do it the way you want, I'm sorry. I love you so much."

The footage was shown in an episode of The Hills which aired in the U.S. on Monday night.
