We don't know how she does it! Kim Kardashian claims she's raising money for U2 rocker Bono's RED campaign to support HIV and AIDS research and treatment -- saying what she did today supports 63,000 days of HIV/AIDS medication for Africa. Uh, really?

Sorry to be critical, but how does standing by some random woman getting her makeup done raise money for AIDS? How does Snapchatting ridiculous, insanely mindless selfie videos raise money for desperately-needed medication for Africa? How is she bringing attention to a cause? How is she encouraging others to participate? Does she even understand what she's doing/not doing?

We caught up with the social media star at the Four Seasons in Westlake Village as she strutted her stuff in short cut-offs, a long tee, and heels. But really, folks -- are we interested in Kim K's charitable work when it involves going to a four-star hotel for 45 minutes, doing a social media post and then moving on? I mean, we'd like to say, "Good for you, Kim! Keep it up!" But somehow this whole "charity" thing seems like a farce!
