LeBron James won the first championship in his career as the Miami Heat defeated the Oklahoma City Thunder in five games in the 2012 NBA Finals. He was named the series MVP in the same season that he won the league MVP.

James celebrated after Thursday's game with teammates and his family, including his fiancée.

Savannah Brinson, James' girlfriend, became engaged to the basketball player at the end of 2011. The MVP proposed to Brinson on New Year's Eve at a party celebrating both the holiday and his birthday.

James reportedly bought the engagement ring for his girlfriend for between $250,000 and $300,000. Brinson has sported the ring at multiple Heat games, and it is said to be between four and five carats.

The two were high school sweethearts and have been dating for years. They have two children together. Brinson and the kids moved to Miami this year after staying in Ohio last season.

Brinson was caught up in some controversy when a rumor was started that she was having an affair with former Wizards player Rashard Lewis. Some thought the rumors, which were never proven to be true, may have contributed to James' poor play in the 2011 Finals.
