Low key besties!

Kourtney Kardashian and Lindsay Lohan grabbed dinner last night in London, and we kind of forgot they even knew each other! Then we remembered that Lilo has a lot of connections to the K clan and it made a lot more sense.

Kim styled the rehabbed redhead before she skyrocketed to reality TV fame, and the Parent Trap star attended her wedding to Kris Humphries. There's also the fact that Kourt's best friend Courtenay Semel dated the former child star for a hot minute back in the day.

Guess who else tagged along for the outing? Lohan's fiance Egor Tarabasov!
