”I actually think he’ll be in Atlanta,” she said. “But that’s okay. We all gotta work.”

And as far as how she'll be celebrating?

“I’m very lucky; I do have a very blessed life,” she told E!. “I do have the day off, which is exciting. I’m probably just going to relax and take time for me, be with my friends and go to the beach.”
