The Jen effect: Miss Aniston's influence is apparent as Justin Theroux shows off new fashionable image

He has already undergone one transformation since becoming Jennifer Aniston's beau going from sporting a scruffy to a sleek style.
But it seems that Justin Theroux has enjoyed a second makeover and the finished product is an even trendier and stylish look.
Justin, 40, has upgraded his hairstyle and his fashion sense and looks like a new man, compared with the one Jennifer started dating.

New look: Justin Theroux has enjoyed a second makeover and the finished product is an even trendier and stylish look

Justin showed off his new look at Skylight Soho while his girlfriend was promoting her labour of love, Five.
The actor displayed his newly tousled hair and trendy style in an all black outfit, matching Jennifer.

Another new look: Justin showed off his new look which includes a youthful hairstyle, and he looks much different to how he appeared in July this year

Justin looked every inch the fashionable man in a pair of dark jeans, a jumper and a black leather jacket for the event.

Although he shyly refused to steal her limelight by posing together, the pair were seen leaving their home together heading to the screening.
Jennifer, 42, wore wide-leg trousers and a vest with nothing but a lacy black bra peeping out underneath; she finished off the ensemble with a simple gold necklace and black heels.
Recently Jen was said to be extremely upset after reading scathing comments from her ex-husband Brad Pitt, who said their marriage was 'boring' the incident is said to have highlighted just how happy she is with Justin.

A source told Grazia: 'Talking about the marriage it's like he's slicing open that wound again. She hates talking about it.'
They added: 'She's so happy with Justin, and he was amazing, doing everything he could to cheer her up.'

Joining Jen at the event were fellow famous ladies Demi Moore, 48, and Alicia Keys, 30.

Moore wowed in a black and geometric patterned column dress, looking far slimmer than she ever has.
The Superwoman singer stunned in a tight-fitting black blazer with leather sleeves, a tight black skirt and animal print accessories.
She brought husband Swizz Beatz as her date for the evening, who balanced out her chic black look with his more laid-back style.
The Lifetime movie is an anthology of five short films exploring the impact of breast cancer on people's lives, and the famous three have directed one each.

Good morning, angels: Alicia Keys, Jennifer Aniston and Demi Moore were a delightful sight on Good Morning America this morning

Today the trio set out to spread the word about the inspiring project, and started with an appearance on Good Morning America.
All three looked stunning, though Keys, by far the youngest, was a fashion disaster in a beige boiler suit - only saved by her natural beauty.
Aniston looked great - so glowing with the flush of newly discovered love that she skipped to the studio, even stopping to pet a dog on the way.

Spreading the word: With such an important subject matter, Jen and Demi are keen to throw all their weight behind the project

Close: Jennifer rested her hand on her friend Demi as she reached for her morning drink, though she doesn't appear to need caffeine

But it was Moore, two years away from fifty, who stole the style laurels.
Divine in leather effect leggings and heels, her tweed blazer ensure she didn't look tacky but rather on trend.
Perhaps 33-year-old husband, and now Two and a Half Men star Ashton dressed her.
Commissioned for US channel Lifetime,  the project is clearly also very much Aniston's baby, she said recently: 'Our hope with Project Five is to entertain, inform and inspire dialogue, research and prevention. Otherwise, our goals are small.'

Hit and miss: Demi could probably give Alicia a few style pointers as her boiler suit was a flop

Classic Jennifer: She didn't push any boundaries but Jennifer looked wonderful in her trusty blazer and vest

'We want these films to move people and empower those affected by breast cancer to stand tall through this challenge, which impacts ALL of our lives, no matter who we are.'
Project Five is Aniston's second foray into the world of directing.
She first sat in the director's chair for 2006 movie Room 10, a romantic drama based in the emergency room of a hospital.
