The glamour model, 31, real name Katie Price, dumped the cage fighter moments after quitting I'm A Celebrity...Get Me Out Of Here! on Monday.
'I watched the TV and it seemed very cruel the way she spoke about Alex,' Carol Reid, 69, tells The Sun.
'He really loved her and gave up a lot for her, and this is how he gets treated by her.
'I can't get through to him at the moment. All I know is that he is in Australia and his phone is off.
'He must be upset. I'm worried for him.'
Alex, 34, flew Down Under earlier this week and apparently planned to propose to Jordan.
