The star, who has revealed she's expecting her first child with husband Sam Burrows, was seen with her bump on display at Glastonbury, and it looks as though she's certainly enjoying her pregnancy.
Jessie, 31, first told fans her exciting baby news back in April, posting a picture to her Instagram account that showed her new pregnancy figure with the caption: 'Dropping this year, and it's not the album X'
Fans were quick to congratulate the star at the time, with one writing: 'Congrats!! And I hope you release more music soon!!!' and another adding: 'This makes me so happy on so many levels'.
Jessie, who is currently working on her third album, has kept fans updated with her progress and took to Instagram over the weekend to share some fun festival snaps.
In the pics, the Tough Love hit-maker can be seen laughing while friends plant kisses on her tummy, and surround her while holding her growing bump!
Jessie married her childhood sweetheart Sam on the Greek island of Skopelos in 2014, a place which holds special meaning for the couple after they got engaged there. Jessie and Sam met when they went to school together in Dulwich, south London, before meeting up at drum and bass nights in nearby Streatham.
The singer has revealed that her hubby has little interest in the world of celebrity, telling ES Magazine: 'Sam couldn't give a s*** about any of it. You have quite a lot of mad moments like when you have to pinch yourself because you're having a drink with Lana Del Rey at Chateau Marmont and she looks so perfect sipping her Shirley Temple and she smells so sweetly and he's just like: "Chateau what?"'
She added: 'He's happy for me, but he'll only come along to support me, not because he's interested in any of it.
'When we went to Glastonbury we passed the VIP area, but he didn't want to go near any of that and that was great. I think that's so good and so important.'
