File this relationship under "Things that make you go hmmmm."
Despite their 15-year age difference, the romance between father of three Scott Disick and teen model Sofia Richie is staying strong.
Over the weekend, the pair, fresh from their whirlwind "taco night"-filled trip to Punta Mita, Mexico, grabbed a caffeine fix in Los Angeles on Saturday. The twosome were spotted holding hands during their quick trip.
In September, the pair were spotted kissing, canoodling and having a grand old party time together. From romantic dinners to kiss-filled outings on yachts and romantic strolls, the twosome seemed to be showing some major PDA everywhere they went.
Of course, this unlikely union between Kourtney Kardashian's 34-year-old ex and Lionel Richie's 19-year-old model daughter has some shaking their heads and others wanting to know more about the duo.
One of those people shaking their heads seems to be Sofia's famous father. "I am scared to death. Are you kidding me?" Lionel told Us Weekly.
Like it or not, it's happening. Take a look at their romance in photos...
