Breakfast club! Brad Pitt and Angelina Jolie treated their twins, Knox and Vivienne, to a surprisingly normal breakfast at the Griddle Café in West Hollywood for their 8th birthdays on Tuesday, July 12. 

The group sat at a booth right near the front of the restaurant, but the A-list parents kept a low profile. Pitt, 52, wore a white T-shirt and beige hat, while Jolie, 41, donned a black top and neutral cardigan with a pair of sunglasses.

“They were super nice and friendly,” an onlooker tells Us Weekly, adding that they “tipped very well.”

It seems like they splurged on their diets for the special occasion, ordering a variety of sweet breakfast treats. They feasted on the “Devil’s Daydream” French Toast (chocolate bread loaded with chocolate chips), the Oreo-filled “Black Magic” pancakes with whipped cream, the honey and cinnamon-flavored “Sow Your Oats” pancakes and a side of eggs.

“Brad and Angelina were super low-key and a bunch of the waiters there didn’t even realize it was them until they stood up to leave,” the eyewitness said. “They were super chill.”

Knox sat next to his dad during the outing and Vivienne sat across the table next to Jolie. After breakfast, the four of them were spotted shopping at a nearby Rite-Aid store.

Besides the twins, Pitt and Jolie also share Maddox, 14, Pax, 12, Zahara, 11, and Shiloh, 10. The couple tied the knot in France in August 2014 after being together for almost a decade.
