Engaged, pregnant or just happily dating? Scott Disick, 34, and Sofia Richie, 19, raised new questions about their relationship after they were given a "Congratulations" cake at dinner in Miami on Saturday night.

TMZ, who first reported the story, spoke with sources who said Kourtney Kardashian's ex didn't propose to the blond beauty. That has now left fans with more questions than answers.

Congratulations Scott And Sofia Pregnant? Engaged? 'Keeping Up With The Kardashians' fans found themselves wondering why Scott Disick and Sofia Richie got this 'Congratulations' cake in Miami.

After jumping from one model to the next the last 12 months, Scott seems to be sticking to one woman for the moment. The father of three has seems to be rather taken with Sofia, who was previously linked to Justin Bieber.

“Since returning to L.A., Scott and Sofia are inseparable. They are spending every day together. Sofia seems smitten,” an insider told People.

The couple packed on the PDA during a boat ride in Miami over the weekend after they saw Travis Scott perform at LIV nightclub. The bizarre couple also made things Instagram official.

So how does Kourt feel about the bizarre relationship? “Kourtney thinks this fling with Sofia is a little weird, but nothing shocks her anymore," a source told Us Weekly. "Kourtney just wants Scott to be his old self. She shares three kids with him, so she'll always want the best for him and will always make sure he's happy."

But other sources say Kourt isn't taking the relationship seriously. The sources point to Scott's track record, saying he never follows through with anything or anyone.
