Jennifer Aniston accepted the Decade of Hotness Award at the Spike TV Awards in Los Angeles last night and showed that her strict diet and exercise routine has paid off. The 42-year-old actress looked better than many women half her age and flaunted her toned physique in a revealing black Azzedine Alaia dress and Manolo Blahnik heels. The strappy mini dress proved that Aniston is still just as smoking hot as she was when she first burst onto the scene as Rachel Green in the TV smash hit, Friends, in 1994. But the actress’s rock hard body does not come without a serious commitment to diet and exercise. The American beauty revealed the secret to her honed body stating, ‘It’s simple. Run, work out every day. I do a lot of running- exercise is so important.’ Aniston has been through a lot over the past few years, with her divorce from Brad Pitt, several subsequent failed relationships and a movie career that has been hit and miss. But one thing that has been consistent is her enviable looks, shiny hair, toned legs and rock hard abs. Aniston’s commitment to her body is paramount and a source on the set of her film, The Bounty, revealed to Life and Style Weekly magazine, ‘She runs before filming starts. We were filming from 6am until almost 11 at night and her body looks amazing.’ The source went on to comment that Jennifer would get up as early as ‘3am to ensure that she stays in tip top condition’ and be sure that she could fit her work outs into the long days of filming.
