JOACHIM & FRED ROCKED BY SHOCK CLAIMS

Wild reports of a secret crush have raised eyebrows in Denmark

Prince Frederik's feud with his brother Prince Joachim has been catapulted to new heights after wild allegations suggested the younger sibling has long been harbouring romantic feelings for his sister-in-law Princess Mary.

"With obvious signs of drunkenness, it seems that the youngest son of Queen Margrethe tried to stamp his lips on his sister-in-law's mouth," a source claimed to Spanish magazine Vanitatis El Confidencial.

"Mary got out of the way as she could and with an unperturbed smile, while Joachim's wife Marie witnessed the embarrassing moment."

The publication also went on to allege that Joachim, 53, was "deeply in love" with Mary, 50, and "it didn't help that in 2007 he announced his engagement to a French girl [Marie] with the same name and a striking physical resemblance".
