Iconic multimillionaire US sports stars LeBron James and Tiger Woods celebrated birthdays on Tuesday with NBA playmaker James and 14-time major golf champion Woods seeking future success despite impressive achievements.

Woods, who turned 39, is chasing the all-time record of 18 majors won by Jack Nicklaus while James, who turned 30, has won two NBA titles with Miami but came home this year trying to bring Cleveland a major pro sports championship, something not seen in half a century.

Four-time NBA Most Valuable Player James passed out of his 20-something days with 23,901 career points, the most of any player at that point in his career in NBA history. He celebrated his 30th birthday, being held out for the Cavs' 109-101 loss to the Atlanta Hawks in Atlanta on Tuesday, with a sore left knee.
