Glowing 4-months-pregnant Kate gets behind the wheel in Birmingham

The Duke and Duchess of Cambridge visited Birmingham today.

They both got behind the wheel for some off-road driving at a Land Rover test course. William steered, with Kate riding shotgun, over the rocky course before she took the wheel.

William and Kate, who have a cocker spaniel, Lupo, were also shown dog whistles. Kate asked about the special whistles whose pitch can't be heard by humans, saying, "There are different pitches for different dogs, aren't there?"

The two ended their day meeting up with children at Aston Villa F.C.'s stadium, William's favorite soccer team. They joined young people involved in the Coach Core training program, a mentorship apprenticeship opportunity sponsored by William, Kate and Harry's charitable organization, the Royal Foundation.
