Longworth, who is one of the new cast members in the Derren Litten comedy, described her outfits on the show as "pretty hideous", but admitted that her partner was a fan.
"My character Same does have some pretty risque costumes!" she told DS. "Plenty of see-through tops and lacy bras and pretty hideous swimming costumes. I had to get over all my body hang-ups and just say, 'I am this character and I'm pretty damn hot right now'.
"My boyfriend actually asked if I could keep one of the swimming costumes!"
Longworth makes her debut in Benidorm tonight at 9pm on ITV1.
