The two NBA stars were on hand for the national team's minicamp practice, and made the announcement in an impromptu news conference alongside team managing director Jerry Colangelo and head coach Mike Krzyzewski.
Durant said he made the commitment to Krzyzewski late Tuesday night, while Love officially made his announcement during the news conference.
Both were members of the United States men's national basketball team that won the gold medal in the 2010 world championships and last year in the London Olympics.
Durant set a record for most points scored in an Olympic basketball tournament with 156 at London.
