The 'It's My Party' singer, who is currently on her 'Sweet Talker UK Tour' gushed about singer-songwriter Luke, who she first met in New York.
Speaking to the Daily Star, she declared: "I am so in love with him. He was booked to support me on tour before we even met. That's how much I loved him as an artist.
"That's before I met him and thought 'I want you to be my husband one day'. It has only been five months but it feels right."
Jessie went public with their romance in November 2014 after posting a photo of Luke on Instagram, saying: "My first ever official #mcm. My man. My crush."
Jessie was previously private about her past relationships, but recently she decided that she no longer wants to "hide".
Speaking on ITV's Loose Women three months ago, she described Luke as "amazing and incredible". She added: I'm really happy."
