'Cause her body's too bootylicious for ya babe!

Khloe Kardashian went to Beyonce's concert at the Rose Bowl in Pasadena last night, and the reality star turned heads in a pair of see-through leggings. WOW! Just wow. Sometimes the flash from cameras can make black clothes appear more sheer than they really are, but surely Khloe knows this by now -- we have a feeling she kinda did it on purpose. I mean, why not? Her body is BANGIN'!

Khloe was joined by older sister Kourtney, who wore an equally sexy outfit, and the ladies looked like they had a blast at the show, which attracted all kinds of A-list attendees. Earlier in the day Khloe tweeted, "I can't have a migraine today!! It's Beyoncé night. No way will I let this f*ck up my night. Mind over matter." From the looks of it, it seems like she was feeling much better by the time Bey took the stage!
