Tabloids have often reported that the actress is expecting her fourth child with husband Ben Affleck.

Water towers are common around London suburbs. The height of the tower provides the pressure for the water supply system, and it may be supplemented with a pump. The volume of the reservoir and diameter of the piping provide and sustain flow rate.
When water is not at peak demand, water is stored in the tower. When it's at peak demand, the city's pumps can only handle so much, and the rest is fed in from the tank at the top of the tower. This helps a community maintain consistent water pressure, no matter what the demand may be.
