So when we caught up with the TOWIE star at the recent Style for Stroke charity event in London, we were keen to hear just how Jess managed to get in such great shape in the lead up to her brother, Mark's wedding.
'I wanted to get back to my fitness after being in Dubai for the hen do, so I've been going to the gym almost every day and trying to detox,' she says.
And whilst Jess is looking fab herself, she may have some competition from her new sister-in-law, after Michelle was voted FHM's Sexiest Woman of the Year.
'I text her saying, "Oh hey sexiest woman ever." She said, "Noooo" but Mark loved it. She's one sexy lady'.
But although we're pretty sure that Jess has a queue of admirers of her own, she tells us that she won't be settling for just anyone when it comes to dating.
'I'm quite fussy. I might meet someone and think I quite like them and then a few weeks later, I may change my mind!'
