Lee Seung Gi is once again proving to be a CF king as he filmed his latest commercial for Pizza Hut's 'New Double Box' with child actor Choi Ro Woon from KBS 2TV's 'Good Doctor.'

While the CF has not yet been released, still cuts show the two of them sitting in the living room with their fictional parents as one big and happy family enjoying a meal of Pizza Hut.

A representative who was present during the filming said, "Ever since the two warm-hearted people met, the filming also felt warm.  Most notably, because Lee Seung Gi was looking at Choi Ro Woon in such a lovable way, jealous female staff members were exclaiming here and there."

You can see the lovable CF and brotherly chemistry once it is publicly revealed in October.
