Over the weekend Rosie Huntington-Whiteley and Leonardo DiCaprio's new girlfriend Erin Heatherton were photographed out and about in Hollywood, and it looks like they had a blast hitting the town.
Not only did Leo let Erin drive his black Lexus for the evening, but it sounds like things are getting serious between the two. It was recently reported that Leo has already introduced Erin to his mother Irmelin, and a source told the New York Post, "The meeting went well and [mom] and Erin were seen laughing. Leo and Erin seemed really happy."
Rosie and Erin have been friends for years, and in a recent interview Erin revealed that Jason Statham's main squeeze is one of her "best friends in the world." Aww!
