Johnson has offloaded the six-bedroom estate in just two weeks and sources tell TMZ that Kardashian is the new owner after spending over $8.4 million on the pad.

The former American football superstar is said to be glad to be far away from Bieber and the drama he has caused at The Oaks in the past year.

He has been vocal about his troublesome teenage neighbor and his sportscar-driving, fast-paced partying lifetstyle and following the singer's DUI arrest in Florida on Thursday, Johnson tweeted, "They finally caught HIM! Glad no one was hurt, no kids in the street. Everyone grows up at some point. Hopefully he learns from it."
