J-Lo will always be Jenny from the Block, even when she's jetting off to North Africa.

Sources tell Us Weekly that Jennifer Lopez, 42, and new beau Casper Smart, 24, headed to Morocco Thursday.

Marc Anthony's ex is scheduled to perform at the launch of the Morocco Mall in Casablanca, and the backup dancer is along for the journey.

Over Thanksgiving weekend, the singer-actress brought her new man along for a vacation to Kauai, Hawaii -- where he quickly bonded with Max and Emme, her 3-year-old twins with Anthony. 

"Casper was great with the kids," an eyewitness tells Us of the dancer, who spent six nights with Lopez, the twins and other family members, including the singer's mom, Lupe.
