The 42-year-old American Idol panelist will embark on a series of concerts with Enrique Iglesias this year but faces legal problems with her four-year-old twins Max and Emme accompanying her.
After her fellow performer and father of her children, Marc Anthony, filed for divorce in April, a court ordered that their offspring should not cross the border of California without prior permission.
Now Jennifer and 43-year-old Marc will both be outside of the state as he kicks off his own gig dates in August.
Court hearing
The What To Expect When You're Expecting star has filed documents asking her estranged husband to arrange a shared custody schedule for the duration of them being away from home between themselves.
However the parents won't find out the court's decision until briefly before they are due to travel.
A court hearing has been arranged for 26 June and Jennifer's tour with Enrique begins in July.
The On The Floor singer has been dating her back-up dancer Casper Smart for the past six months, and the hunk knows how to make her feel special.
A source told People magazine: "He treats her like a queen. Casper centres everything on Jennifer."
