Pop singer Britney Spears says her marriage to Kevin Federline is fine but she is spending a lot of time alone.
According to newsweek.com, the couple in Florida for vacation stayed in separate rooms and even rented two different houses.
A friend said: "She did it to get away from Kevin."
Spears didn't attend the party that Federline organised with eight of his friends. Despite all this, Spears claims that everything is fine with the marriage.
A US weekly had experts analyse Spears' body language on a TV show recently. The singer closed her eyes when she said that her marriage was doing fabulous. Experts say she was not being honest.
Jack Timarco, FBI polygraphs examiner and criminal profiler, said: "When a person covers or closes their eyes, it often means they are getting ready to tell a lie."
