The happy couple tied the knot at her home in California on Monday night, following just over seven months of dating.
They told the magazine, in a joint statement: “We couldn't be happier to begin our new journey together surrounded by our closest family and friends.”
It’s thought that Drew threw the bride-to-be a wedding shower on the day before she and Benji got married, with a rehearsal dinner following at Cameron’s home that night.
This is the first time either of the couple have been married.
Speculation first began brewing that Cameron and Benji might be planning to get married as far back as July, after she was seen wearing a ring on her engagement finger.
However, she refused to confirm or deny whether the rumours were true in an interview with Cosmopolitan last month.
