With all of the excitement over Kim Kardashian
and Kanye West
's Italian wedding
, it would be easy to overlook Scott Disick
But Khloé Kardashian
made sure that her sister Kourtney
's boyfriend, 31, was not forgotten, lightheartedly posting to Instagram
side-by-side mugshots of herself and Disick (whom she refers to as LD – Lord Disick).
"Happy birthday to my partner in crime @letthelordbewithyou I love you LD!!" she wrote.
Each mugshot was from a past DUI incident. Kardashian served less than three hours
of her 30-day sentence for a DUI in 2008, and Disick was arrested in 2001 for driving while intoxicated in Riverhead, New York.
