After a whirlwind trip to France and Switzerland, Kylie Jenner and her boobs are back home in Los Angeles -- right where they belong!

On Sunday, the 17-year-old showed off her midriff leaving as she left a friends place in Beverly Hills. After hanging with her friend, the reality star drove off in her Range Rover.

The teen's been back a few days but we hadn't seen her show off those tatas she loves to showcase until yesterday. Over the weekend, the teen celebrated big sister Khloe's 31st birthday at Pinz Bowling in Studio City on Saturday night.

Last week, Kylie and her older boyfriend caused some major drama on their European vacation. In case you missed it, Tyga performed at club Envogue Geneve in Geneva, Switzerland on Thursday night, and after practically bailing on his set (he was supposed to perform for an hour and only rapped for about ten minutes), the owner ran out of the club and started yelling for Tyga. Kylie and Tyga were both in their car ready to leave, but Tyga jumped out of the vehicle, only to sneak back inside after someone in the owner's posse flashed a gun.

Tyga tweeted, "Sum Club owners just think they own u just Kuz they pay u to come to they lil club for a hr." The rapper wrote, "I ain't nobody slave. Don't harrass me and my people when we tryna chill n sh*t. Every since I came in the game in 2008 people tried to tarnish my brand. mislead who I am."

What a great guy!
