Why Khloe Kardashian Skipped the MTV Video Music Awards

— -- Kanye West was honored with the Michael Jackson Video Vanguard award at Sunday night's MTV VMAs and his wife Kim Kardashian, mother-in-law Kris Jenner and sisters-in-law Kourtney Kardashian and Kylie Jenner were there to support him.

But some were wondering, "Where's Khloé?"

Turns out, she was babysitting her eldest sister's five-year-old son Mason Disick.

"Mase and I are having a raging slumber party!!" the reality TV star tweeted.

Still, it's clear that Kardashian, 31, caught the show from home. After West announced at the end of his speech that he planned to run for President in 2020, she made her support known by posting a "Mr. West for President" banner on Twitter.

West can also count on Kourtney Kardashian's vote. After the show, she shared a photo of herself standing in front of the White House with her sisters.

"Keeping Up with the Kardashians Season 427: White House Edition," it read.
