They're just your average family... kind of.

Angelina Jolie and Brad Pitt treated twins Knox and Vivienne to a birthday breakfast at The Griddle in West Hollywood on Tuesday, and we can't believe how old they're getting! The kiddos turned 8-years-old with a feast of pancakes, and the whole group kept it low-key without much attention from other diners.

"They were super nice and friendly. [They] tipped very well,” a source dished to Us Weekly. The actress donned an understated black top and neutral cardigan, while the A-list actor kept it casual in a white t-shirt and beige hat.

Their meal selection? “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, according to the mag.

"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. They were super chill," the eyewitness added.

Following the outing, they headed to Rite-Aid to do some shopping. Stars - they're just like us!
