The big guns! Twins Karissa and Kristina Shannon put on bikinis into the hot-tub

It looks as though the Playboy twins have lost their touch.

The busty blonde sisters, Karissa and Kristina, were challenged to lure Kirk Norcross and Frankie Cocozza into the hot-tub but failed miserably.

Jedward returned to the Big Brother house in the form of 'cheeky cherubs' and have been trying to cause some mayhem among the housemates.

Here come the girls: The twins change into bikinis hoping that Kirk and Frankie will follow them to the hot tub

The brothers asked Karissa and Kristina to take part in today's task via a speaker placed in the stone cherubs in the garden.

The boys told the girls to persuade the two frisky housemates into the spa and then told them to get the boys to strip naked before stealing their shorts and running off.

The model twins first set upon Kirk and said to him: 'Kirk do you want to get in the hot-tub with us?' to which an unimpressed Mr Norcross replied: 'oh yeah probably.'

Even ladies man Frankie wasn't interested in getting wet with the girls and he used the water temperature as an excuse to avoid taking a dip.

Frankie, 18, said: 'That's f***ing freezing. That's not hot, you'll be freezing if you sit in that.'

The former X Factor contestant continued: 'You get in, I'm not. I couldn't think of anything worse girls.'

Fingers crossed: The sight of the girls in swimwear wasn't enough to get Frankie and Kirk into a cold hot tub

As the 18-year-old swaggered back into the house the twins went to plan b and changed from their warm clothes into some racy bikinis.

Equipped with their curvy bodies on show the twins waltzed through the house hoping that the sight of their tan lines would entice the boys into the hot-tub.

However, Frankie was still too scared of the 'freezing' water and said: 'Its not hot enough girls.

Mission failed: Frankie said: 'I couldnt think of anything worse' as the girls decided to put towels on
