Backstreet Boy, Nick Carter has been granted a temporary restraining order against his younger brother, Aaron after alleging he threatened to kill Nick’s pregnant wife.

The singer said the legal move came “in light of Aaron’s increasingly alarming behaviour”.

Aaron must now stay at least 100 feet away from Nick, his family and their Las Vegas home.

In response, Aaron Carter said he was “astounded” by the accusations.

Nick Carter, whose band had hits with such songs as “Everybody” and “I Want It That Way”, announced in May that he and wife, Lauren were expecting their second child.
