Leonardo DiCaprio Girlfriend: Is He Dating Erin Heatherton? [PHOTOS]

The first time was luck. The second time, coincidence. The third time...well fine, he's a supermodel magnet.

After dating Gisele Bündchen and Bar Refaeli, 37-year-old Leonardo DiCaprio nabbed himself another supermodel girlfriend; This time he's dating Victoria's Secret model Erin Heatherton.

DiCaprio and Heatherton were seen together in Sydney, Australia where he is shooting a new film, The Great Gatsby.

According to AceShowbiz, 22-year-old Heatherton flew from New York to Sydney just to spend some time with DiCaprio. The couple, rumored to be dating, was first seen on Dec. 9 at a martial arts even followed by dinner on Sunday at Barrio Chino in Sydney, according to The Telegraph.

There were times when they weren't really talking but then they would get chatty again and laugh and stuff, an unnamed witness told The Telegraph. If they're not 'together' I would say they are very close.

According to Radar Online, Heatherton was seen picking up $1,700 of sexy lingerie at a store, and since that's her line of work, there's no telling if the new smalls are for DiCaprio or just because.

Since he arrived in Sydney, where he is renting a house in the Vaucluse area, DiCaprio has been seen with models on a daily basis, namely Alyce Crawford and Kendal Schuler and the forty models who reportedly attended his birthday last month.

Dating Heatherton, a blonde Victoria's Secret model dubbed the Sexy Nerd of VS angels, is just another day for DiCaprio, since he has dated three blonde supermodels over the years, including international sensation Gisele Bündchen and Bar Refaeli.

Leonardo DiCaprio and Erin Heatherton are reportedly flying back to New York together on Friday for the holidays, the Melbourne Herald-Sun reported.
