Nicole Richie hasn't been a well bunny while filming the new series of The Simple Life.
But she's now found out why she has been feeling poorly.
The star has been told she has hypoglycaemia, or low blood sugar as it's more commonly known.
The diagnosis follows Nicole being hospitalised for dehydration earlier in March.
Her spokesperson confirmed to People magazine:
"In her ongoing effort to focus on her well-being, Nicole has recently been diagnosed with hypoglycaemia or low blood sugar.
"(She) is taking steps to manage it."
A rep for the show added: "Nicole has reported to work each day and the results have been fantastic."
There has been no comment as to whether the condition is linked to the star's weight.
