Kim Kardashian posted this snapshot on Twitter over the weekend and wrote, "Rawwwr!!! Halloween Costume shopping." We're not sure if this one will make the final cut (after all, we're sure boyfriend Kanye West has to sign off on what she's wearing), but it's definitely a sexy ensemble!

Kim is currently in Miami shooting her reality show, and last night Kanye was involved in a minor scuffle with a photographer after the two had a romantic dinner at Prime 112 steakhouse.

"Kim and Kanye had a very discreet dinner in a private room with the curtains drawn at Prime Hotel while Reggie was with his girlfriend across the street at Prime Italian," an eyewitness told In Touch Weekly. "Kim and Kanye got there around 5:30pm and made a big scene when they exited two hours later ... They were yelling at photographers and one of them even asked Kanye about Reggie being so close by; he didn't seem too happy about it. Both Kim and Kanye looked a bit stressed out."

But when a female pap yelled out, "Kim did you know Reggie is here [in Miami] having dinner? Did you wanna go congratulate him on his pregnancy?" Kanye apparently lost it, rushing after the photographer in an attempt to grab her camera. After the pair drove off in a Rolls Royce Phantom, the female pap told other photographers, "Kanye West just tried to beat me up." Yikes!
