Demi Moore has announced she is ending her six year marriage to Ashton Kutcher. The 49-year-old actress said in a statement that she is filing for divorce with 'great sadness and a heavy heart'.

Hinting at Kutcher's infidelity, Demi said: 'As a woman, a mother and a wife, there are certain values and vows that I hold sacred, and it is in this spirit that I have chosen to move forward with my life'.

Moore added that it's a trying time for her and her family and asked for people to respect her privacy.

Immediately after the announcement, 33-year-old Ashton posted his own statement on Twitter.

He wrote: 'I will forever cherish the time I spent with Demi.

'Marriage is one of the most difficult things in the world and unfortunately sometimes they fail. Love and Light, AK.'

The pair are still following each other on Twitter in wake of the announcement and Demi's handle remains @mrskutcher - something she may now consider changing.

Despite their dignified statements, Demi is now gearing up to battle it out over their $290m fortune after enduring public humiliated because of his alleged infidelity. The Two And A Half Men star allegedly shared a night of passion with party girl Sara Leal, 22, at the Hard Rock Hotel in San Diego. Texas-born Leal sold her story on Kutcher weeks after the fling, which took place on Ashton and Demi's sixth wedding anniversary, September 24.

Demi scarily skinny

In the weeks that followed, Demi appeared to be suffering under the strain of her marriage breakdown, becoming gaunt and scarily skinny - reportedly dropping down to just 7st (98lbs) which given her height of 5ft 5in is considerably underweight. On Thursday, the actress -- who turned 49 the next day -- was photographed leaving a nail salon in L.A. looking thin and stressed out while revealing her protruding chest bones. Looks like the stress surrounding her alleged marriage drama with Ashton Kutcher is quickly aging the 48-year-old actress.

month in an apparent bid to heal their relationship

The couple were accompanied by some close friends along with their Kabbalah instructor Yehuda Berg and photos emerged of the pair sat around an outdoor fire. It was first time they were pictured together since news of Kutcher's alleged booze-fuelled one-night stand broke.

Moore and Kutcher wed in September 2005. The couple's relationship hit the headlines in recent months as rumours swirled about Kutcher's alleged infidelity. The Two And A Half Men star allegedly shared a night of passion with party girl Sara Leal, 22, at the Hard Rock Hotel in San Diego. Texas-born Leal sold her story on Kutcher weeks after the fling, which took place on Ashton and Demi's sixth wedding anniversary, September 24.

Moore, who was previously married to Bruce Willis, started dating Kutcher in 2003. They married two years later. In May last year Demi talked about wanting to start a family with Kutcher in an interview with Elle magazine - something that never came to pass. The actress has three daughter with her ex Willis - Rumer, 23, Scout, 20, and Tallulah 17.
