In reply to Stephy Tha Lambily.

She rarely, if ever, lipped when she made that statement though... When her voice reached critical status in 2000 is when lipping was absolutely necessary.
Besides you make it sound like Mariah goes on these extended tours. Her tours are extremely limited, and she is every open about her dislike of touring.
TV performances are another story. She's done countless amounts of them. The crowds aren't charged for attending those performances though so Mariah doesn't need to apologize for a free performance.
