James's decision came on the first day of free agency, just 20 hours after the market officially opened.
James' agreement with the Lakers was announced through a simple press release sent by his agent, Rich Paul, which says James, a 14-time All-Star, three-time Finals MVP, and two-time Olympic gold medalist, was joining the Lakers.
James spent the week vacationing in Anguilla, and hopped aboard a private Gulfstream jet in the morning to fly to the Los Angeles area.
By moving West for the first time in his career, James will face a stiffer competition night in, night out, with Steph Curry's Warriors, James' Rockets and a whole lot of stacked teams crowding the playoff race.
For the Boston Celtics, James' exit from the Eastern Conference further cements their status as a team with potential to advance to the NBA Finals.
James and the Cavaliers had been beaten in three out of four NBA Finals by the Warriors since 2015. If the Lakers strike out this summer, they are likely to try to make a splash in the summer of 2019.
James had left Cleveland in 2010 for the Miami Heat, where he reached the NBA Finals four times, going 2-2, before departing for the Cavaliers, vowing to bring a title to Cleveland, his home region, having grown up in nearby Akron. The deal is worth $154 million over four years. He averaged 27.5 points in a league-best 36.9 minutes per game in 2017-18. Last month, Gary Payton fueled up the Los Angeles rumors when he revealed that Lebron's 13-year old son had committed to playing at Sierra Canyon High School next year.
Retired Lakers icon Kobe Bryant also reached out to show his support and excitement, tweeting, "Welcome to the family @KingJames #lakers4life #striveforgreatness @JeanieBuss @MagicJohnson and RP well done!"
