I was born in Jacksonville, Florida, and is the daughter of Michele, who works in insurance, and Joe Greene, a U.S. Marine who now owns his own concrete business. I grew up in Middleburg and Jacksonville, and went to University Christian School before transferring to Wolfson High School when I was in tenth grade. I'm moved to Los Angeles, California, at the age of 17 to pursue an acting career.
I have an older brother named Joe, who still resides in Jacksonville with my parents.
I'm is good friends with her Twilight co-stars, particularly Kellan Lutz and Jackson Rathbone and Nikki Reed whom i knew before filming of the series began. I grew up watching football and is a Florida Gators fan.
I was also seen attending a Green Bay Packers game against the New York Giants with Jonas and Jessica Szohr at Lambeau Field in 2010.
