Yesterday was Justin Bieber's birthday. The Biebs went all out for his 18th birthday, in the afternoon Justin went parachuting and later had a fancy dinner with friends, but his real birthday gift was real estate. Justin is planning on buying not one BUT two LA mansions! Right now he has his sights set on the former homes of the Kardashians, the Jacksons, Britney Spears, and Ashton Kutcher. Justin described Ashton's home as "really dope." Justin wants to buy one mansion for himself and one for his mom. It's kinda sweet, but at the same time it's such a waste of money! The two cheapest mansions would cost a total of $14 million! Justin is 18, he doesn't need a mansion. (tmz)
