Last week, after months of claiming that they are "just homies", the couple were spotted kissing poolside on Miami Beach.
Days later Scott, 34, posted a *different* kissy snap with Sofia, 19, to his Instagram story which led peeps to believe that the pair are up to something.
Then on Saturday night, the rumour mill went WILD after friends of the pair snapped pics of a celebratory dinner.
In the pics, S and S are (once again) making out surrounded by friends and in front of them is a dessert plate with 'Congratulations Scott and Sophia' written in chocolate.
And yes, they wrote 'Sophia' not 'Sofia' *face palm*.
But that's beside the point!
Unless the pair are celebrating ~finally~ going Insta official, we're low-key inclined to believe that this could be an engagement!
Just days before this mysterious occasion, Scott was spotted buying a $10K diamond ring in New York with Madison Beer.
At the time it was believed that he was buying a gift for Madi, but perhaps she was helping him pick out the perf bling for Sofia!
TMZ have confirmed that the announcement is definitely something major, but none of their sources could reveal exactly what it is.
So far neither party has confirmed or denied the rumours but watch this space for more updates!
