One of the most famous weathergirls (albeit more for her personal than professional life) Ulrika Jonsson shot to fame at the end of the 80s thanks to her Swedish blonde locks and sexy smile.
She went on to host 'Gladiators' and become a regular guest in 'Shooting Stars'. During her time as a weathergirl, like most she face her share of bloopers, including the time when a double entendre caught her off guard and she couldn't stop laughing.
