Kim Kardashian is reportedly on a strawberry only diet.

The 'Keeping up with the Kardashians' star is said to be trying out yet another fad diet, which requires her to eat nothing but strawberries for each meal of the day.

A source told The Sun newspaper: ''She's giving it a go a few days of the week.

''She has strawberries for breakfast and lunch and strawberry smoothie snacks inbetween.''

In addition to only taking part in the diet for a number of days out of each week, she's also allowed to have a cheat meal every now and again and reportedly plans to indulge in alcoholic treats.

The source continued: ''She [Kim] joked that it's OK to have champagne and strawberries in the evening.''

However, the 33-year-old beauty - who has 12-month-old daughter North with husband Kanye West - is not the first celebrity to limit herself to the fruit.

Victoria Beckham was criticised for her minimal diet while accompanying her former soccer star husband David Beckham to Portugal for the UEFA Euro tournament in 2004.

One of the other soccer players' wives said at the time: ''She just eats strawberries and turns away all the great breakfasts and salads everyone else tucks into. Most days she has only one meal and that is strawberries.

''Sometimes she just sits there drinking mineral water while we all tuck in. It's a bit strange.''
