Dappy only ate once a day while recording 'Bad Intentions'.

The 'No Regrets' rapper was so focused on making his debut solo album, he didn't eat or sleep properly for months.

He said: ''I could've kept going adding to the album but when I lost all the weight in my face and my body I thought 'I got to stop.

''My metabolism was running crazy. We was sleeping at eight in the morning and waking up at six in the afternoon.

''Eating once a day - so you can imagine four months of that. I'm only just coming round to normal life again now.''

Dappy - real name Costadinos Contostavlos - also said he will be ''devastated'' if all his efforts don't pay off with him scoring a number one record in his native UK on Sunday (28.10.12).

He told the Daily Star newspaper: ''If it doesn't go to number one I will be devastated. I'm going to curl up in a ball and cry.

''If I don't go number one what am I gonna do? It's over. Obviously I got Taylor Swift and Lawson also releasing albums and I'm s**t-scared if I tell you the truth.

''I got a dream to fulfil and kids to feed.''
