It’s gotta be hard being Kourtney Kardashian. I mean, it’s gotta be harder being Khloe Kardashian, but still. If I was Kourtney, I would try to avoid ever being photographed in a bikini next to Kim because there’s just no competition here. Kourtney is a stunner – no question about that. She has the sort of body that would make a man beg. But Kim – Kim has that ass and there is just no competing with that thing. Kim’s ass is like crack – no pun intended. It’s addictive. J-Lo herself has to bow down and accept that Kim has stolen her crown. Kim Kardashian is the Queen of the Caboose and poor Kourtney isn’t even in the Royal Court. Here in South Beach, the sisters have fun playing on the beach and enjoying some quality sister time, but you can’t help but wonder if somewhere in Kourtney’s head, she isn’t hoping that Kim will decide to be modest and cover up that famous rear.
