Fatboy Slim and Zoe Ball have split up.
The 53-year-old DJ - whose real name is Norman Cook - and the 45-year-old presenter insist they are still "great friends" but their "exciting adventures together" are now over, 17 years after they tied the knot.
The couple - who have kids Woody, 16, and Nelly, six, together - said in a statement: "With great sadness we are announcing that we have separated.
After many exciting adventures together over the last 18 years we have come to the end of our rainbow.
"We are still great friends and will continue to support each other and raise our beautiful children together, living next door but one."
Insiders claim the couple had had a number of rows over Zoe's desire to go out partying.
A source told The Sun on Sunday newspaper:
"There have been a series of arguments, all over the same issue - Zoe wants to go out and have fun, and Norman would rather stay at home.
"His sobriety was incredibly hard-won and he doesn't want to compromise it.
"Zoe completely understands that, but she is in a very different place. She doesn't want to be sat on the sofa of an evening having a cup of tea.
"Despite being previously tee-total, she loves a party and will get stuck into a night out.
"Recently they've struggled to reconcile their different attitudes and it's caused a lot of tension."
Problems are said to have began in August, when they terminated a trip to Ibiza early following a row.
The source added: "There was a row about her drinking and it all came out then. Zoe is supposed to be dry but she has been going out drinking more and more with girlfriends."
The couple split previously in 2013, but later reconciled.
