British reality TV star Kerry Katona has been admitted to a rehabilitation clinic to seek treatment for depression. The former Atomic Kitten star has been readmitted to London's The Priory for treatment for bi-polar disorder. TV network MTV confirmed it has suspended filming of her reality TV show Crazy In Love. Her publicist denies her readmission was connected to reports her husband Mark Croft had cheated on her. He says, "Everything is good in terms of her marriage and career-wise. "She suffers from bi-polar disorder. Some days she is down. There is nothing different at the moment." The 27-year-old is pregnant with her fourth child.
