The 'Waiting for Tonight' singer let her hair down at the theme park in California, as she dared the popular rides including Dumbo The Flying Elephant, the children's train and Gadget's Go-coaster in Toon Town.
Jennifer, who was joined by other family members, laughed and screamed as she sat beside her kids, proving that her superstar status doesn't stop her from doing normal activities!
Meanwhile, her adorable five-year-old twins, Max and Emme, beamed from ear to ear.
Jennifer, 44, who attended the resort without her dancer boyfriend Casper Smart, dressed down in a white T-shirt and blue trousers, keeping her hair loosely tied back.
It seems like Disneyland is a popular place with showbiz children and adults alike, as last week, Victoria and David Beckham took their kids there for a trip!
Meanwhile, last week (24 August), Jennifer performed her chart-topping hit 'Jenny from the Block' with Taylor Swift when she was invited as a guest on her 'RED' tour.
Jennifer joined Taylor on the fourth night of her show at the Staples Centre in Los Angeles, and brought plenty of sparkle to the performance in a silver sequin jumpsuit!
After the performance, Jennifer tweeted, "Thank you for inviting my family to be a part of yours @taylorswift13!!! #RedTourLA," along with an Instagram photo showing a collage of snaps of the pair in a dressing room.
Meanwhile, Taylor said: "Sang Jenny From the Block with @JLo tonight at Staples Centre. STILL FANGIRLING OUT ABOUT IT."
