If Bradley Cooper and Zoe Saldana are truly a couple, they’re sure playing coy about the romance.

The two actors were busy promoting The Words at Sundance Film Festival on Thursday afternoon in Park City, Utah — but didn’t pose next to one another during the red carpet arrivals. The two actors seemed in good spirits though, even as costar Dennis Quaid sat down between them. Zoe smiled widely as she put her arm around Dennis and Bradley looked on.
