Kerry KatonaKerry KatonaIt’s not been the smoothest of times for Kerry Katona.

And it seems that all this has taken its toll on her.

It appears that pregnant Kerry has fallen into depression again...

And has checked herself back into The Priory.

Some peeps are worried that she’s had a breakdown, as filming of her fly-on-the-wall MTV1 show Crazy In Love has been suspended.

But her spokeswoman last night insisted Kerry is “just a little down” and is staying at the clinic to recharge her batteries.

She has had a lot on her plate lately.

Earlier this month it was claimed her hubby, Mark Croft, had cheated on her - something both she and Mark say they know is not true.

Kerry was also fending off reports that said she had taken cocaine on New Year’s Eve.

It’s the fourth time Kerry has been checked in to rehab over the years.

But her spokeswoman Nicola Phillips, of Max Clifford Associates, told The Sun: “Kerry has not suffered a nervous breakdown.

“She suffers from bipolar disorder and is just feeling a little down.”
