Flu and Fancy Footwork Frolic on 'Dancing with the Stars'

The flu bug has dominated the "Dancing with the Stars" competition this season. Derek Hough had to sit out a few weeks ago and on Monday night, Lacey Schwimmer was replaced by Anna Trebunskaya to partner Mark Dacascos.

Mark spoke to Lacey earlier in the day and reported to ET, "She's getting a little bit better, but still not 100%." Meanwhile, the other pro dancers and celebrities are fighting through the sniffles and coughs as they samba, quickstep, and foxtrot closer to the coveted mirror ball trophy. As Donny Osmond spun partner Kym Johnson in their quickstep, the under the weather entertainer felt as if "the room was spinning around."

Aaron Carter, who was awarded with "Len's first ten of the season," put his game face on, saying, "Nothing could take me from this competition, no flu, nothing."
