Stewart is keeping herself busy with work ever since she split from her "Twilight" co-star in May.
She recently announced that she will be a part of a sequel to "Snow White and the Huntsman" despite rumours that the first film's director Rupert Sanders was responsible for her break-up with Pattinson.
Meanwhile, Pattinson, 27, went shopping for a ping pong table. He later drove his truck here Saturday with the unknown girl on the passenger seat, and a brand new table tennis table in the back seat, reports thesun.co.uk.
Pattinson took the stranger lady to his mansion.
