AceShowbiz - R&B singer Michelle Williams (II) has been forced to postpone a chat on actress and TV presenter Mo'Nique's U.S. talk show after her flight to Atlanta, Georgia was canceled due to heavy snowfall in the state. The former Destiny's Child member was due to sit down with the "Precious: Based on the Novel PUSH by Sapphire" star on "The Mo'Nique Show" on Tuesday, January 11 to discuss her upcoming stage stint in new play "What My Husband Doesn't Know".

Williams had been visiting her sick father in her native Chicago, Illinois over the weekend and was due to fly to Atlanta on Monday, but her flight has been grounded due to the bad weather. She writes on her Twitter.com blog, "flights cancelled to atlanta today! was supposed to tape the monique show tomorrow! :( i need the snow in atl 2 (sic) melt fast! i already (had) places to go and people to visit all planned!"

The "Survivor" hitmaker hasn't had much luck with her travels in recent weeks - she had to cancel a trip to New York last week after falling ill, and she only just made it back to the U.S. for Christmas after extreme weather conditions in the U.K. threatened to leave her stranded in London for the holidays.
