The beautiful duo was appropriately clad in Disney gear as they posed for photographs in front of Sleeping Beauty's Castle, Zayn sporting a gray Mickey Mouse sweatshirt while Perrie opted for a tan beanie.
The couple took in all of the attractions, but their favorites included the thrilling Big Thunder Mountain ride and Peter Pan's Flight.
Zayn and Perrie stayed at the fairy-tale Disneyland Hotel, and they were treated to a special visit from Disneyland's most popular and famous resident: Mickey Mouse.
The delightful trio posed for a bunch of cute and silly snapshots together, and Zayn snapped a few selfies with the notable cartoon character and his ladylove on his phone.
At the end of the fun-filled day, the lovebirds enjoyed the park's nighttime fireworks spectacular, Disney Dreams.
Zayn recently opened up about his relationship with Perrie and revealed how he is keeping the romance alive and staying in shape for their upcoming wedding.
"I do try to impress her still, I do try to do a bit of exercise," Malik told E! News. "I don't want to completely let myself go."
