Alex opened up to her campmates Ruby Wax and Shona McGarty about her and Jess' romance this week.
The star shared: 'I think before her, I never knew happiness.'
This prompted Ruby to ask how the couple first met, to which Alex replied: 'She approached me in Chiltern Firehouse...
'I was in there with my friends and she just walked up to me... [it was] really ballsy and I was like, I like your ballsiness, and then the spark was just instant and then yeah...we fell madly in love.'
Continuing, Ruby then queried whether marriage would be on the cards for Alex and Jess.
Alex and Jess have been together since June 2023.
