Speculation is rife the Obamas are having trouble in their marriage.
Several publications have reported that the couple is going through unspecified marital problems which are threatening to overshadow Michelle's upcoming 50th birthday celebrations, News.com.au reported.
Sources revealed that the problems aggravated when the First Lady remained in Hawaii to spend time with her friends while her husband returned to Washington with their two daughters from a Christmas break.
According to the National Enquirer, the first couple is now sleeping in separate White House bedrooms.
Barack had previously admitted that they have had several ups and downs in their marriage, as they have to deal with the pressures of dual careers.
