Brooke Mueller's parents look happy to be spending time with their grandkids Max and Bob. Seems as though they're getting a great workout, too!

Since Brooke is busy with rehab and daddy Charlie Sheen is traveling for his tour, Brooke's mom Moira Fiore and stepfather Jon are taking care of the adorable twins.

Charlie has reportedly said he'd like to take the boys with him on the road, but Brooke retains custody of the boys.
