Stephen Amell's Surprise On-Set 'Arrow' Guest Is Ridiculously Cute

Stephen Amell's adorable daughter made an appearance on the 'Arrow' set.

The fourth season of "Arrow" may be well under way, but that doesn't mean that the cast is done filming. In fact, star Stephen Amell has documented the cast's past few days of filming, including a surprise on-set visit.

Who graced the Arrow set most recently? None other than Stephen's super adorable young daughter, Maverick, who made a stop on the set on Saturday!

And although we know Stephen was super stoked, we're sure Maverick had a good time as well as the cutie just celebrated her second birthday this past Thursday.

This wasn't the first time Maverick visited her proud dad on set. This past summer, Maverick and wife Cassandra Jean spent a month in New York while Stephen filmed the sequel "Teenage Mutant Ninja Turtles: Half Shell."

So will Maverick be making any film or tv appearances with her dad anytime soon? We'll just have to wait and see.
