As it turns out, Winfrey suffered a sprained back on her big day after trying to lift an enormous arrangement of flowers sent to her by close pal and business partner Tyler Perry.
"I FEEL SO BAD," lamented Perry to his Facebook page on Wednesday. "I like to send really large flower arrangements to people for whatever occasion. Well, I sent one to Oprah yesterday for her birthday. She strained her back picking it up. No joke!"
