TMZ has learned Ellen DeGeneres hurt her back over the weekend -- and it's so bad that she's doing this week's shows from a hospital bed!
The bed will be placed center stage on Ellen's set. She'll lob questions at Ryan Seacrest and Lindsay Lohan from a supine position. Seacrest will appear on tomorrow's show and Lindsay will talk to the bed on Wednesday.
Ellen was scheduled to do a show on a Delta Airlines 767 later in the week. It was a big deal that was sponsored by American Express. But we're told that on doctor's orders, Ellen can't travel, so the trip will be rescheduled.
