Mila and Ashton's belated honeymoon
Before marrying Mila, Ashton Kutcher was famous for being Demi Moore's other half. His relationship with the Ghost actress began in 2003 after the pair met at a casual dinner with friends.
Ashton was 25 and Demi 41, but despite the 16-year age difference the pair moved in together shortly afterwards, setting up home with Demi's three daughters from her previous marriage to Bruce Willis.
They married in September 2005, and Punk'd star Ashton became Hollywood's most famous toyboy - with constant reports of Demi's use of cosmetic surgery to retain her youthful looks and her desire to have a baby with her younger husband.
In November 2011, Demi announced their marriage had ended with the statement; "It is with great sadness and a heavy heart that I have decided to end my six-year marriage to Ashton,"
Ashton began dating Mila in mid 2012, yet the couple had first met way when they were cast in That '70s Show in 1998, when Ashton was 20 and Mila just 14.
They played on-screen grilfriend and boyfriend, Jackie and Kelso, until 2006, and Mila has revealed that Ashton was her first on-screen kiss.
Low-key romance is Mila's style. She was first linked with former child-star Macaulay Culkin in 2002, and dated the Home Alone star for eight years, with little media attention.
Mila (31) and Ashton (37), along with their nine-month-old daughter Wyatt, recently took a road trip through the Californian countryside in a RV camper.
It's thought to have been the couple's belated honeymoon, following them saying 'I do' earlier this year. Hollywood's newest power couple have yet to reveal the exact date of their nuptials.
