Big day: Jennifer Aniston made her mark in Hollywood today as she attended her Hand and Footprint Ceremony at Grauman's Chinese Theatre in Los Angeles
He may have hidden in the car for her Horrible bosses premiere last week, but Jennifer Aniston's new boyfriend Justin Theroux was front row and centre for his new leading lady today.
The 39-year-old was spotted just metres away from the 42-year-old actress at Grauman's Chinese Theatre, beaming and applauding his girlfriend at her Hand and Footprint ceremony in the forecourt of the Hollywood landmark.
And in a clear sign that he is serious about his lady love, Justin even shaved off the bristly beard he has been sporting for the last few weeks for the official occasion.

A one point the actor and screenwriter burst into fits of laughter on the sidelines, while Jennifer tried to keep a straight face in front of the crowd.
The actress couldn't wipe the smile off her face as she placed her perfectly manicured hands and well-heeled feet in the cement, which she also signed and dated.

She even blew a kiss to her beau in the crowd.
'She was beaming,' an insider told People magazine. 'She couldn't have looked happier.'
Jennifer moved away from her favourite safe black attire for her special day, opting for a very girly Prada floral number, a carefree choice for the actress, who is said to have fallen head over heels for her new man.

As always she wore her blonde bob in a sleek and coiffed style.
And to make way for the messy cement, Jennifer had slipped off the matching gold ring and watch she shares with Justin off her left hand, while the actor proudly displayed his accessories from the front row.
Also on hand to support the former Friends star was Jen's buddy comedian Chelsea Handler, who cuddled up to the mega star in a sophisticated black dress as they posed for pictures.
'All my neighbours looked more like Snooki,' Chelsea joked.

But noticeably absent was her best friend Courtney Cox, who was a surprising no show.
The Friends co-star has been by Jennifer's side for most of her momentous occasions, including her high-profile wedding to Brad Pitt, but she wasn't spotted anywhere in the crowd.
Co-star and close friend Jason Bateman toasted the actress with a funny and endearing speech about his good friend.
Following the ceremony, the group headed to the nearby Hollywood Roosevelt hotel for a celebration.
Jennifer's appearance today could well spell one of the last for the actress in the realms of the showbiz world.
Jennifer, who earned a staggering $27m last year, is said to be taking a 12-month hiatus from the 'office.'

She plans to focus all her energy on her love life instead of her film career, according to insiders.
The Horrible Bosses star, who will release three movies this year, is going to wave goodbye to Hollywood - and say hello to be being a full-time girlfriend to her new beau.
Jen's taking a year off from work to enjoy herself,' an insider told American magazine, Us Weekly.
The magazine is reporting that a second source familiar with her schedule confirms that after Horrible Bosses and the October release of Wanderlust, the only thing on her schedule is developing The Goree Girls, her production company's project about singers in a women's prison.

Although she kept him hidden while she walked the red carpet at last Thursday's Horrible Bosses premiere in Los Angeles, Justin was pride of place at the drinks later that night.
After meeting up inside the premiere, the couple spent an hour and a half at the after-party before heading to the Chateau Marmont to meet friends, including her Courteney Cox.
An onlooker told People magazine: 'They were super cute. He had his arm around her and kissed her on her cheek. They were whispering in each other's ears.'

Reluctant to take time away from Justin, she is keen for the Tropic Thunder and Iron Man 2 screenwriter to collaborate on the script with her.
'She's impressed by his ability to find humour in dry material,' the source told Us.
The career move comes after the former Friends star has been increasingly open about her flourishing relationship with Justin.
