The Atlanta Hawks edged out the Boston Celtics by a single point in Game 1 of their Eastern Conference first-round playoff series. Not wanting to risk any more close calls, Atlanta unveiled its secret weapon: Justin Bieber.

Now, many Hawks fans were dismayed, because of the so-called Bieber curse, which has caused some teams to experience bad luck when the Grammy winner has been in attendance or visited a team for a game. But things might be turning around for the former NBA All-Star Celebrity Game MVP. NBA teams are 6-4 in their first home game following a stop on Bieber's current "Purpose World Tour" -- and that includes the Hawks, who won Game 1 after Bieber took over Philips Arena on April 12 and 13.

Bieber also paid a visit to the Houston Rockets earlier this month, and they went on to win their final three regular-season games to qualify for the playoffs after spending much of the season below .500.

The Hawks aren't worried about any curse -- at least not one from Bieber.

This won't be the last time Bieber and the NBA playoffs intersect, either. If the first-round series between the Cleveland Cavaliers and Detroit Pistons extends beyond four games, Game 5 in Cleveland is scheduled for the same night as a Bieber concert at Quicken Loans Arena.
