But don't get TOO excited, it's not what you think!
The singer, 22, put on the cute display of affection after arriving at the Once Upon A Smile Grand Ball 2015 at The Hilton Hotel in Manchester (Saturday 2 May).
Getting down on one knee - the universally recognised position of declaring undying love (and proposing!) - Jake pretended to serenade his lady, Little Mix star Jesy.
And Jesy is wearing the BIGGEST smile on her face!
Looking absolutely gorgeous in a striking red frock with matching lippy, Jesy looks like she's up for a fun evening with her beau - who was performing at the charity event with his band.
Before getting on stage, he tweeted: "Me and my boys at the Once upon a smile ball. Excited to perform. Great to be here."
Jake is the acting and singing son of Coleen Nolan and Shane Richie. He and Jesy first confirmed their romance in September last year, after being linked together in the summer.
Jesy recently admitted that she is "so bloody in love" with Jake. He in turn has admitted he's "in love" with Jesy.
