Brown, who recently won joint custody for his child, has vowed to make some major changes in his life for his little princess including staying off wild parties and drinking to stupor.

"Chris is weening himself off drinking and other stuff he does because he wants to be healthy, have a clear mind, and be a completely conscious and sober parent. He doesn’t want anyone or anything clouding his mind or judgment," a source tells HollywoodLife.

The source also adds that, "He wants to witness every little single thing Royalty does with a clear mind. He wants to fill his mind with sober memories of her doing the smallest things like tying her shoes, being potty trained, you name it. His life and world is now Royalty and everything else that doesn’t serve that he’s cutting out!”  the insider continued.

The 'Beautiful People' singer has also upped the security at his Los Angles home to make sure no harm or robbery attack comes to his family.

Sources close to the singer say he’s even begun calling it "Operation Homeland Security" and that mansion of his will be safer and more secure than the White House. "He’s already given pink slips to several members of his security team and he and his mother are currently interviewing new security members to protect Chris, Royalty and their home 24/7," says a source.

Just how much has fatherhood changed 'bad boy' Chris Brown?
