(1) It's none of our business. Just because a woman or a man is, say, 30 and still single and not attached to a member of the opposite sex, that does not automatically mean that person is gay. And if he/she is gay, who cares? I'm not interested in any of the skater's personal lives -- as my diatribe on the "Up Close and Personal" thread clearly shows.
(2) Tonya -- "I know nothing." Remember Sgt. Schultz in "Hogan's Heroes"? I wouldn't bet the ranch that she knew, but neither would I bet the ranch that she did not know. Only she and her conscience know for sure.
(3) Maybe Michelle needed a new look. Maybe Frank felt that the judges were going to pull another "Linda Fratianne" on him at the Olympics (that's his story, not mine, folks). Who knows?
Michelle fired Frank, but he got over it, and so did she. Life goes on....
(4) Only Irini and her husband can answer that one. If she is expecting, that's lovely. If she's not expecting, that's lovely, too!
