As per a source, Justin is yet to grow up and is a child at heart. He had the tree house built for a reason. He got it so that he and his buddies could escape a daily routine to drink and play cards. Now, this is something that young boys used to do. Tree houses were meant for their meetings and a chill out zone.
This 29-year-old pop heartthrob is an ex Nsync member and has gone to the extent of even banning his girlfriend Jessica Biel from entering his new domain. It is also said that the tree house has a 'No Girls Allowed' sign on the door! This is utmost childish or should we say boyish, since such signs are something that are utilized by young boys.
Justin had bought his £5 million worth property at Mulholland Drive way back in 2002 and has installed a basketball court and lately, a five-hole putting green so that he can master his golf skills there.
Justin plays off a remarkable six handicap and even has his own course, the Big Creek Golf Course near Memphis. He is also the host of a yearly charity edition of the Professional Golf Association (PGA) Tour event along with the Justin Timberlake Shriners Hospitals for Children Open situated in Las Vegas.
The SexyBack singer has recently installed a huge den on the grounds of his Los Angeles mansion; he has done so as to have a private space to hang out with his buddies and unwind.
