Brentwood Mria Shriver Katherine Schwarzenegger

They seem so close!

On Saturday, Maria Shriver and Katherine Schwarzenegger did some mother-daughter bonding time in Brentwood while ex-husband Arnold Schwarzenegger took out their other daughter Christina for a bike ride in Santa Monica.

Even though they're not together, the pair look to make sure their family relationships doesn't falter. With the girls out and about with their parents, wonder what Patrick and Christopher were doing?
