The 'DNA' singer's beloved mum Janis has the hots for the music mogul - who signed them to his SyCo record label after they won 'The X Factor' last year - and would love to on a date with him.
When quizzed by We Love Pop magazine on what she would really like to ask Simon, Jesy revealed: ''Can you take my mum on a date? She fancies him. All the older ladies fancy him!''
Jesy wants to buy her mother a traditional British tea room in Cornwall, South West England, when she and her bandmates start banking some serious cash.
The 21-year-old star - who is joined in the girl group by Perrie Edwards, Leigh-Anne Pinnock and Jade Thirlwall - said: ''I want to buy my mum a house in Cornwall. She wants a little tea room on the beach, with a little flat above.
''So, fingers crossed, if we do earn a bit of money, I'm getting her that straight away.''
