Dwight Howard's estranged wife, Amber Howard, is accusing the NBA player of locking her out of their home. In a 911 call obtained by TMZ on Thursday, March 12, Amber (who also goes by Amy Luciani) tells an operator that she is unable to get inside her house because the gate code has allegedly been changed. "Whenever he gets upset, he locks me out of our estate. We live in a 35,000-square-foot big home," she claims in the call. "It's Dwight Howard from the Lakers. Any time he gets upset with me, I come home, the gate's locked. He just did it again.
