Their recent nuptials were the talk of Hollywood: together for four years – and engaged for three – Jennifer Aniston and Justin Theroux should still very much be in the throes of newly-wedded bliss.
Indeed, and despite their lengthy engagement, the actors were seen to have a rock-solid union.
But the couple, who said their vows during a top secret ceremony on August 5 at their €20m LA home, have now been shaken by claims that their three-week-old marriage is OVER.
Specifically, the most recent edition of Life & Style magazine claims that Ms Aniston, 46, can "no longer fake the happiness".
A source goes on to explain that she and Mr Theroux are "fighting non-stop," and that 45-year-old Justin is simply “happier when he’s away from her than when he’s with her”.
“She can’t even fake the happiness anymore," the Life & Style source adds. "Jen is wondering if she made the biggest mistake of her life by marrying Justin."
Whether the rumour is true or not has yet to be confirmed by the couple's representatives, however, one thing does seem certain: they are currently apart – albeit for filming.
He has now begun work on his new HBO series, The Leftovers in Texas, while Jen is filming in Atlanta for Mother's Day.
Following their wedding, the love-birds had enjoyed a sun-soaked trip to luxurious Bora Bora for their honeymoon – and, unusually, they were joined by a gaggle of pals including Jason Bateman and Courteney Cox.
If true, Justin and Jennifer could lay claim to one of showbusiness's shortest marriages.
Members of that notorious group include the likes of Kim Kardashian and Kris Humphries, Kid Rock and Pamela Anderson, and Britney Spears and Jason Alexander.
