Some celebrity couples such as George Clooney and Amal Alamuddin prefer to live their lives with huge fanfare while others such as Mila Kunis and Ashton Kutcher opt for the quiet life, getting married in secret.

Jupiter Ascending actress Kunis, 31, is said to have confirmed her wedding to the Two And A Half Men actor during an appearance on The Late Late Show With James Corden this week.

If reports are true, the former That 70s Show co-stars aren't the first celebs to have tied the knot secretly. IBTimes UK takes a look back at the celebrity couples who evaded the paparazzi on their special days...

Scarlett Johansson and Romain Dauriac

A clerk at Granite County, Philipsburg, Montana, confirmed that the Lucy actress had tied the knot with the French journalist on 1 October 2014. However, the news was not revealed to the public until a couple of months later in December. A source told the New York Post: "They kept the wedding a big secret because they both wanted privacy."

Janet Jackson and Wissam Al Mana:

Reports had initially claimed that the very private couple had planned a lavish ceremony costing millions of dollars, so it came as a huge surprise when the All For You singer and billionaire businessman announced that they had married in 2012.

Jackson and Al Mana didn't announce the news to the public until 26 February 2013 with the following statement: "The rumours regarding an extravagant wedding are simply not true. Last year we were married in a quiet, private, and beautiful ceremony.

"Our wedding gifts to one another were contributions to our respective favourite children's charities. We would appreciate that our privacy is respected and that we are allowed this time for celebration and joy."

Angelina Jolie and Brad Pitt:

After more than 10 years together and six children later, the Mr & Mrs Smith co-stars finally got married in a very low-key ceremony in August, 2014 at France's Chateau Miraval. Although that was their official white wedding, Jolie later revealed that she and Pitt, 50, had actually signed the papers in California before their big day.

"Before the wedding in France with the kids, Brad and I were already married in California. As Americans, we couldn't marry legally in France," Jolie told Italian magazine Io Donna.
