Although the Keeping up with the Kardashians reality star is heading to Canada next weekend for an official alcohol-fueled birthday bash, a source close to Jenner says she will have a more intimate birthday party at her new mansion the night before turns 18, which is on Aug. 10.
"Kylie is having a party at her new home on Sunday night because she wants to be around all of her friends and family the moment she becomes an adult on Sunday night at midnight," says the source.
"It is sort of a birthday and housewarming soiree and she is inviting basically everyone!"
As RadarOnline.com previously reported, Jenner and her boyfriend Tyga have been forced to keep their relationship away from the public eye since they first started dating a year ago because of their age difference and the fact that Jenner is still considered to be a minor.
"The one thing Kylie is looking forward to the most is being able to be Tyga's girlfriend wherever they go," says the source.
"She really cannot wait until this whole charade of them just being friends is over because it is getting really old."
