Brad Pitt cruised around on one of his motorcycles in LA on Thursday while Angelina was across the country in DC with Maddox and Pax speaking at the World Refugee Day conference. For the most part, Angelina's subject matter was pretty heavy but she also spoke to Anderson Cooper a bit about her family and an upcoming first birthday for the twins, Knox and Vivienne. She said, "I do have the twins (born July 12) and I just had Shi in May. We have so many kids that we just have year-round birthdays. … It’s a lot of fun now ’cause the older kids are old enough to help plan the birthdays for the younger kids. So it’s one of the great pleasures of life, the birthdays." Before Knox and Viv turn the big one year, this weekend's another special day for the family of eight — Father's Day for Brad dad.
