There's a lot people want to know!

Scott Disick and Sofia Richie spent all day together yesterday in LA after returning from Miami, and photographers asked them about everything from a possible engagement and that "congratulations" cake to Khloe and Kylie's surprise pregnancies. They said nothing and acted like they were too cool for school, but LD would have gotten a verbal beat down from the K clan if he opened his mouth.

Later in the evening, the couple went to Nobu for dinner, and we're dying to know who pays for all their outings. The reality star has some good dough from Keeping Up with the Kardashians, but Sofia is Lionel Richie's daughter! We have a feeling the 19-year-old model is footing the bill for all these fancy meals, vacations, and private jets.

That said, it sounds like The Lord is pulling out all the stops to charm Justin Bieber's ex.

"Sofia has been interested in him for a long time. She feels like she knows a different side of him and that they are good for each other. She is falling hard and thinks this is the real thing," a source dished to E! News.

"They are inseparable right now and not leaving each other's side. Scott is totally romancing her and she is under his spell. He took her away to Santa Barbara [last] weekend and is spoiling her with shopping trips and sweet gestures," the source added.

We wonder how long these two will last?
