The Jolie-Pitts never ignore any occasion to celebrate family functions in an upbeat way, and birthday celebrations rank high on their priority list. Angelina Jolie Pitt and Brad Pitt celebrated the seventh birthday of their twins -- Vivienne and Knox -- Sunday by taking them and the rest of the brood ice skating. The kids reportedly had a blast.

The parents took the twins and their other kids -- Maddox, 13, Pax, 11, Zahara, 10, and Shiloh, 9 -- ice-skating in Van Nuys, California, Us Weekly reported. The twins also were accompanied by few of their pals, who joined the birthday celebration. The family hired a bus and headed for Iceland Ice Skating Center. “Knox and Viv were bundled up with snow hats and mittens. They were really excited about it,” a witness told the magazine website.

The kids spent around two hours skating and also indulged in special bumper car rides on the ice. “They were spinning around getting dizzy and had a blast. Some of the kids were holding hands as they skated and it was really sweet,” the witness said. The kids were completely “wiped out.”

The family reportedly gave the twins toys for their presents. Jolie and Pitt were spotted taking Shiloh and Pax for toy shopping Friday at the Toys ‘R’ Us store in Glendale, California, Just Jared reported.

The Jolie-Pitts try to keep a low profile in public. Jolie recently took Shiloh on a trip to Syria to meet the refugee families. The couple also were spotted coming out of a Subway restaurant Monday, TMZ said. The couple reportedly ordered “two Meatball Marinara footlongs, one Chicken Teriyaki sandwich, and a few kids' meals.” Their total bill amounted to $44 and the couple also left a $6 tip, the website said.
