Marvin Humes and Rochelle Wiseman have delayed their honeymoon for five months.

The JLS hunk and The Saturdays singer are set to wed during the London 2012 Olympics - somewhere between the end of July and the first two weeks of August - but will not be able to enjoy the traditional post-marriage holiday because of their busy work schedules.

Rochelle is heading to the US to film a new reality TV show with her bandmates Una Healy, Mollie King, Vanessa White and Frankie Sandford, while Marvin is touring the UK with JLS.

The 23-year-old pop beauty said: ''We're going to have a honeymoon at Christmas because we have to fly straight to America to film our reality show. Marvin and I will go away then instead as the music industry is dead around that time.

''We are returning to the Maldives because that's where Marvin proposed. It's very special and fits in nicely.''

Rochelle, 23, has also claimed she has spurned the pre-wedding diet most brides-to-be put themselves on and has actually been eating a lot during the build up to her big day.

However, the '30 Days' singer has continued to lose weight because she has been so ''manic''.

She added to the Daily Mirror newspaper: ''I am eating so much but maybe I've lost weight because I've been manic and am always on The Go. I eat little and often, so maybe that's the secret.''
