We really didn't think these two would be together for more than a month!

Scott Disick and Sofia Richie are practically inseparable these days, so it was no surprise that we caught them holding hands after a romantic dinner date in Calabasas last night. The pair just returned from Aspen, and they're already back to their routine of eating out and spending Lionel Richie's money.

The teen model is LD's first serious girlfriend since he split with baby mama Kourtney Kardashian, and while he's taking the relationship seriously, he's still in shock things with Kourt are done for good.

A source tells X17:
    "Scott is happy with Sofia, but he's having a hard time accepting that things with Kourtney are over. There was always the possibility that they'd reconcile, until Sofia and Kourt's boyfriend Younes came on the scene. It's feeling really real. The Kardashians are the only family he has now that both his parents have passed away, and he worries that they will eventually forget about him like they did with Lamar. If it wasn't for his kids, he'd be in a really dark place."

Sofia is clearly head over heels and expecting a proposal down the line, but The Lord has a long way to go before he's ready.
