In a since-deleted Facebook post, the 44-year-old writes, “Okay since Will Ferrell is talking, I’ma talk-ing.

After making her grand entrance, the singer revealed why she made him switch seats. "Sometimes I like this side better and sometimes I like that side better…it depends on the lighting," she explained.
