Oprah Winfrey is angry. At herself.

The talk show host has gained 40 pounds over the last few months, as she now admits to tipping the scale at approximately two bills. Oprah says she's "fallen off the wagon."

In the January issue of her O Magazine, Winfrey adds:

"I'm embarrassed... I can't believe that after all these years, all the things I know how to do, I'm still talking about my weight. I look at my thinner self and think, 'How did I let this happen again?'"

Does Oprah need to lose weight?
