She's been rocking a sleek bob for the past few months.
But Alice Eve has now had a makeover thanks to some hair extensions, and debuted her new look as she attended a Star Trek press conference in Tokyo, Japan, on Monday.
The 31-year-old star looked chic and glamorous, with her newly long locks teased into loose curls, wearing a cream silk camisole and black maxi skirt.

Alice has been doing her best to promote the new Star Trek movie, which is released in Japan later this month.
And last week, Alice attended her very first Star Trek convention in Las Vegas, where she chatted to fans about her role as Dr. Carol Marcus in Star Trek Into Darkness.
As the question session began, Alice was asked about a scene in the film in which she strips to her underwear - displaying her toned, lithe figure in the process.
However, Alice insisted she has no idea why the underwear scene caused 'all the ruckus', adding that a similar scene in which Chris Pine goes shirtless as Captain Kirk didn't have the same effect.

Alice also hinted that she has already signed up to reprise her role as Carol in another Star Trek movie, to coincide with the 50th anniversary of Star Trek in 2016.
She said: 'We’re all looking to make another Star Trek.'
The British actress added that she would like the next film to continue to explore a possible romance between Carol and captain Kirk, and admitted the prospect of her character getting pregnant on board the ship would be 'interesting'.
She said: 'Obviously I would like to have a romance with Kirk. I think being pregnant in space would also be interesting and raising a child in space, also be worth investigating.'

Meanwhile, in real life, Alice was recently romantically linked to polo player Nic Roldan.
Alice and the 'Prince of Polo'made their first public appearance together at last month’s Rolling Stones concert in Hyde Park. They went on to Mick Jagger’s 70th birthday party in Mayfair following the performance and left arm in arm.
Roldan, who was born in Buenos Aires and raised in Florida, is Alice’s first boyfriend since her split from poet Adam O'Riordan last year.
Alice, who dated Rafe Spall and Rufus Sewell, previously spoke about her struggle to find the right boyfriend.
She said: 'I can’t get into an unmade bed; I can’t sleep with shoes anywhere near me - they have to be in a cupboard - and I absolutely hate a messy car.'
