"With absolute love and respect we made a decision to separate as a couple earlier this year", Fergie's representative told E! "We are and will always be united in our support of each other and our family".
When asked how she keeps her eight-year marriage "spicy and fresh" on KTU's 103.5 in NY on Monday, the "Dutchess" laughed awkwardly before going into detail about her latex getups that she keeps out of her 4-year-old son Axl's reach.
The 'Glamorous¿ singer and Duhamel recently celebrated their eighth wedding anniversary in January.
In the end, the source says that Fergie's "fun and outgoing" personality and Duhamel's "charming and relaxed" outlook couldn't co-exist.
The topic of her sex life came up after Fergie addressed speculation that she and Josh were contemplating adoption.
It's hard not to take to breakups like these personal and believe that true love no longer exists, but I really thought Fergie and Josh Duhamel were built to last.
The couple even shared a few snippets from their fun getaway which showed no signs that they were going through marital issues.
She later said she had sought him out because "I had read in a magazine that he had a naughty dream about me".
In 2015, Fergie told Allure that their work schedules were built around their son and their marriage. "She's an incredible mom".
Fergie said she didn't bring any of the costumes with her to NY. "(We) have a lot of love for our son and have a good time together", he added.
Josh, being the sweet guy he is, denied the allegations, despite Nicole's threat to reveal some texts that the one night stand did happen.
With Josh wanting to focus more on his family and wanting Fergie to be more of a traditional mom, it's possible he wasn't happy when she instead chose to make another album.
