While Kenzie could be seen carrying a reusable Starbucks cup, Chad kept his Stanford hat pulled low on his face in an attempt to avoid the paparazzi.
Meanwhile, a slew of rumours have surfaced surrounding casting for the upcoming transatlantic series of Torchwood.
According to Entertainment Weekly, Chad may be up for the role of funny-but-tough CIA agent Rex Matheson.
Also under consideration is Enver Gjokaj, who starred as Victor in Joss Whedon‘s recently cancelled series Dollhouse.
The final piece of casting news is that Greek actress Amber Stevens is thought to be first choice for the role of another CIA operative called Esther Katusi.
The upcoming fourth series of the Doctor Who spin-off is scheduled to air next summer.
