Sophia Bush dismisses Topher Grace dating rumours

Sophia Bush has laughed off rumours she is dating fellow TV star Topher Grace after they were spotted enjoying a date.

The One Tree Hill actress sparked speculation of a romance with the That '70s Show star after they were recently seen getting coffee together in Los Angeles.

The reports came after Bush split from boyfriend of six years Austin Nichols in February (12), but she insists her relationship with Grace is strictly platonic.

She tells Usmagazine.com, "Topher has been one of my dearest friends for six years. We have coffee all the time and he is actually a great sounding board for me with sort of how to be prepared with all things sitcom."
