Jessica Simpson JSIMPSONTONYAI030208_14.jpg Jessica Simpson may be used to the finer things in life - but she's willing to get down and dirty if it'll help boost the troops' morale!

According to Page Six, the blonde bombshell is currently scheduled to depart today to return to Kuwait to perform for servicemen stationed overseas. (She's not going alone, though - she'll be supported by the Pussycat Dolls, the band Disturbed, and comic Carlos Mencia.)

But apparently, Jessica's not making this trip easy on herself - a source told the mag that the Texas rose will be bedding down in a sleeping bag and a bunk!

"Jessica will be roughing it," a source told Page Six, stressing that the singer will be getting "no special treatment".

How brave of Jessica - she may only be getting the tiniest taste of what a soldier's life is like, but that doesn't mean she's not in for one hell of a learning experience!
