FINALLY! Mr. and Mrs. Justin Bieber are ready to put down roots in their new $8.5M Beverly Hills mansion and we've got the EXCLUSIVE pix of their new estate and what they're doing to amp up their privacy.

For the time being, Justin and Hailey are spending time at his Montage Laguna Beach residence -- they split their time between there and the Beverly Hills residence but have opted for the beach locale lately because it's closer to where Justin's receiving treatment for depression -- but more on that later ...

The couple plunked down just under $10M for the 6,100 square foot remodeled transitional-style home. The home was built in the 1930s and was recently remodeled by designer Charles Infante. The home boasts 5 bedrooms, 7 bathrooms, a library and a home theater. The state of the art kitchen includes a wet bar and wine cellar for entertaining guests.

We spotted landscapers delivering trees to add privacy to the property before Justin and Hailey officially move in, which we imagine will be soon. The home's on a quiet cul-de-sac near neighbors Victoria and David Beckham. Maybe they'll have backyard barbecues together! Check out our gallery of their new digs below and video of the landscape work they were having done this morning ...
