It's the first time Emma has been pictured since rumours surfaced that she was on a break from actor boyfriend Andrew Garfield.
Reports surfaced in the US earlier this month that Emma and Andrew had decided to take some time out from each other because of their hectic working schedules.
Emma's currently in Los Angeles, while Andrew is far away in Taiwan working on his new movie.
A source told People that the split was only temporary, saying: They are just separated for work," the source says. "Andrew is overseas. They are both busy with their careers and have not seen each other."
Neither Emma nor Andrew has commented.
