Kendall Jenner is now 18 years old.
In honor of the occasion, she has received multiple porn offers... rented out Six Flags Great Adventure... and been the center of attention at a masquerade-based party hosted by her famous family last night.
The latter event went down at Los Angeles eatery Mastro's and included Khloe Kardashian, Kim Kardashian, Kyle Jenner and Kris Jenner, all hiding behind masks for the camera.
Watch this video to see what we mean:
"Happy 18th Birthday to the sweetest girl I know," Kim Tweeted to her half-sibling in honor of this milestone. "I hope your adult years are filled with happiness & so much [love]."
Kendall mostly wore a red-and-gold glittery mask for the party, which also included her good friend Spencer Johnson.
Khloe, meanwhile, went with a bejeweled cat mask and plaid jacket.
