According to reports from the US, the good-looking couple became engaged on Christmas Day during a holiday to Hawaii to celebrate Joe's 38th birthday.
While neither Sofia nor Joe have confirmed the rumours, Sofia did post a very loved up photo to Instagram two days ago publicly declaring her love for handsome Joe.
Alongside a picture of them hugging, she said: "Happy birthday to my love and best friend, to the one that makes me laugh like crazy! Have a healthy, wonderful year babe!"
Despite Sofia, 42, and Joe not yet confirming the engagement, fans have been quick to send their congratulations to the couple, with many branding them the "hottest" and "cutest" pair around.
Engagement rumours were sparked when Sofia was pictured wearing a diamond ring while sunbathing by the pool.
A source told E! News: "I've never seen two people so truly in love. The way they talk to each other, touch each other. It's incredible."
Sofia and Joe began dating earlier this year (though Joe is known to have had a crush on gorgeous Sofia for longer than that!)
Colombian-born Sofia was previously engaged to businessman Nick Loeb. She announced in May 2014 that engagement had come to an end, citing work commitments as a problem.
The star is mum to son Manolo, 21, from a previous relationship.
