Just when we thought Kerry Katona was thinking straight, she goes and make us doubt her again.

According to the Mirror, Kerry has allowed her ex husband, Mark Croft to come back into her life after she recently split up with Adam Waldron.

We think Kerry really needs her head testing...

A source revealed: “As soon as she dumped Adam, Mark was on the phone to her. They've been talking nearly every day. It's been easy for them to reconnect. Kerry's even given him back his stereo she took when they split. We all know he is no good for her. Having him back in her life can only end in trouble.”

Whilst everyone is trying to make Kerry see sense, Mark thinks he still has a chance.

Mark reportedly told a friend: “I still love Kerry, and want to win her back. I want to prove to Kerry that I am a decent person, and I think we have got a chance of making things work.”

We're sure Kerry's PR team won't be happy about this...
