The 31-year-old kept her five-year relationship with the Def Jam executive private, but says of finally talking more about her love: “I wanted to let people know that we’re not a secret—we’re just private. Secret relationships are shady, and it’s never been that. Five years into our relationship, we’re no longer at the beginning—we’re established now. We’re in a great, strong place where any negativity cast our way won’t affect us. It was a big birthday for him—he turned 40—and I felt like, ‘I want people to know that I love you, and I think you’re freakin’ amazing.’"
