Popstar Justin Timberlake has built a tree house in his garden to escape with his friends.
The 'SexyBack' singer has installed a giant den on the grounds of his Los Angeles mansion, to provide himself with a private space to hang out with his friends, National Enquirer reported.
"Justin's still a kid at heart. He had the tree house built so he and his buddies could escape to drink and play cards," a source said.
The 29-year-old pop heartthrob has even banned his girlfriend Jessica Biel from entering his new pad.
"He even posted a sign saying 'No Girls Allowed'," the source added.
Since Timberlake bought his 5 million pounds property at Mulholland Drive back in 2002, he has installed a basketball court and, more recently, a five-hole putting green so he can master his golf skills.
