DiCaprio dumped Heatherton because he 'is not ready to settle down'

Leonardo DiCaprio reportedly dumped Erin Heatherton because he didn't want to settle down.

The 37-year-old 'Inception' star - who has previously romanced Blake Lively and a string of top models including Gisele Bundchen and Bar Refaeli - parted ways with the 23-year-old American supermodel last week after almost a year together because she wanted to take their relationship to the next level.
