She is best known as FBI agent Dana Scully on The X-Files, a role that came with a brunette bob and a uniform.

But Gillian Anderson appeared dramatically different as she visited the Chateau Marmont on Saturday night in Los Angeles, alongside gal pal Suki Waterhouse.

The 46-year-old actress was instead a blonde bombshell with her much lighter locks as she dressed in a sheer black gown over a strapless nude sheath.

Meanwhile, fans will be able to see Gillian back in the role of Dana Scully in the impending future, as she will soon be reuniting with her co-star David Duchovny for an X-Files reunion project.

David, who played FBI agent Fox Mulder, recently told The Observer that the reunion ‘is going to happen pretty soon,’ confirming the swirling speculation of a comeback.

‘If you’d asked me this question 10 years ago, I would have said: yes, I’ve had enough,’ he said.

‘But at this point, it’s almost like going out on a greatest hits tour. It would be a lark. And I think it’s going to happen pretty soon.’

They will be making a 'limited' return as their X-Files characters, as neither has 'the energy for a full season,' David said.

According to IMDb, the untitled X-Files reboot is scheduled to debut in 2016.
