Kylie Jenner Files Docs to Secure 'Kylie' Booze

Now that Kylie Jenner's legally allowed to drink ... why not get in the booze biz?!

Kylie has applied for trademarks for "Kylie" and "Kylie Jenner" ... two names she's already trademarked for different goods. But, this time she wants to slap those marks on spirits, liquor, wine, alcohol cocktail mixes, prepared wine cocktails, non-alcoholic cocktail bases, energy sports drinks, smoothies, beers ... plus use the marks for restaurants, bars and cocktail lounges. 

As we first reported ... Kylie expanded her business just last month filing trademarks for "Kylie Baby" to make strollers and all kinds of baby products. The reality star didn't stop there ... she also filed for a trademark for "Kylie Hair" to pump out dryers, curling irons and all kinds of stuff.

Kylie, of course, is already a global brand thanks to Kylie Cosmetics, which is what got her inducted into the Billionaire's club. Expansion, baby!!!
