Model Chrissy Teigen has taken aim at reports suggesting her marriage to John Legend is in trouble after celebrating the couple's fourth wedding anniversary.

The stars hit headlines on Wednesday (13Sep17) after editors at In Touch Magazine ran an article declaring Chrissy's relationship with John was crumbling, with a so-called insider claiming they were "fighting nonstop".

Chrissy, who is known for using social media to speak her mind, came across the tabloid on Thursday (14Sep17) - the same day as the couple's anniversary - and made it clear the "exclusive" allegations were ridiculous in a post on Instagram.

She shared a close-up picture of their image on the magazine's cover, which featured the headline, "Chrissy & John on the Brink of Splitting", and captioned it, "Oh in touch go f**k yourselves, you exclusively dumb pieces of trash (sic)".

Chrissy's scathing comment was posted hours after she uploaded a photo of herself and John all dressed up as they prepared to celebrate their special date.

"Do you know what to-day is," she wrote beside the snap. "#itsouranniversary".

John also took to Instagram to celebrate with fans and express his love for his stunning wife, the mother of his baby daughter Luna.

"Anniversa-date (sic)," he captioned a sweet shot of Chrissy kissing his nose. "Married 4 years today. Met 11 years ago yesterday. I love this woman deeply."

The model and little Luna have been keeping John company on the European leg of his Darkness and Light Tour, which continues in Leeds, England on Friday (15Sep17).

Both Chrissy and John, who exchanged vows in Como, Italy, have been posting pictures from their family travels online, with Luna even getting to spend time with London Mayor Sadiq Khan during the R&B star's concert at the city's O2 Arena on Wednesday (13Sep17).

Alongside a snap of the musician carrying Luna as they posed beside the Mayor, John wrote, "Luna met Mayor Khan backstage! (So did I!)".
