She also address media rumors about her relationship, reiterating that she and LaValle are very happy together: "He's my best friend and I'm his. We're sorry that some weirdo had to make up a story to sell to try and ruin us, but honey we are very secure in our relationship and I know and trust my man, he wouldn't hurt me or our family. He's a real man. So we will pray for you and hope one day you can find happiness. The wedding is still on as scheduled and it will take the apocalypse to change that."
