Kylie Jenner and Tyga are so in loooove!

The 18-year-old reality star and her main man were all about each other when they attended Republic Records' VMAs after party last night in West Hollywood, CA.

For the spicy soiree, Kylie, who changed her hair back to black, wore a sexy black bandage dress and nude sandals. Tyga looked like he was ready to shoot some hoots in a t-shirt shorts and athletic shoes. The rapper was clearly ready to get his party on -- he was carrying a bottle of Hennessy into the party! Someone looks like he's pre-gaming pretty hard! Looks like someone is pulling Kanye West's 2008 VMAs move!

Meanwhile, Tyga just came out with a new music video starring his teenaged lady love called ... wait for it ... "Stimulated." Gag.

Some of the oh-so-sweet lyrics include, "I’m at the bank, I’m penetrating / I’m putting in, I’m penetrating / I’m getting big, I’m stimulated,” raps Tyga in the innuendo-filled lyrics. “I touched the bitch, she disintegrated / Up in flames, I’ve been the flamest / I’ve been the hottest, you’ve been the lamest."

Aww too cute!
