And now the glamour model has openly nominated her estranged husband's 'mistress,' naming her in an Instagram video.

NICOLA MCLEAN'S LIFE IN PICTURES

Standing bikini-clad on the beach, surrounded by hunky men, Nicola makes her nomination before being covered in ice-cold water by her obliging helpers.

Last week, Nicola publicly outed her husband's 'mistress' on Twitter and Instagram, posting a snap of the woman wearing one of her jumpsuits in a club in Las Vegas.

'This is my jumpsuit @prisalterado you've been shagging my husband for months he has lied to both of us' she wrote on Instagram.

But it seems Nicola is now finding time to laugh at the situation, goading her love rival into taking the ice bucket challenge.

Tom Williams' alleged mistress is a waitress who works in California, who he apparently met while working as a concierge in Sin City.
