Kylie Jenner hopped on a plane to Montreal on Saturday night, and the starlet, who turned 18 on August 10, looked beyond thrilled to continue her birthday celebrations up north.

Kylie will be partying it up at Beachclub Montreal, and seeing as the drinking age in Quebec is 18, we have a feeling the starlet will be drinking and gramming over the weekend. As long as it's legal, right? Kylie will also be getting a massive cake from Cakes par Haute Couture, and the five-tiered creation and other party treats cost around $3,000 and will feed about 150 people.

Of course, beachclub owner Olivier Primeau estimates that over 5,000 people will show up to the bash, so only a select few will get to actually party with the reality TV princess. And how much is she getting paid for this appearance? When asked about a report that Kylie was getting somewhere between $100,000 and $200,000, Primeau told local reporters, “It’s not a free visit. We invited her and we pay to have her here.”

The previous day Kylie posted a pic from the pool at Casa Aramara in Punta Mita, Mexico, and she showed off plenty of side boob in a revealing one-piece swimsuit. "relax w meee," she captioned the shot. Kylie was joined by boyfriend Tyga on the vacay, along with sister Kendall and pals Hailey Baldwin and Pia Mia. Guess she's not a kid anymore! Then again, she hasn't been for quite some time...
