Karly and Sophie swap bras

FHM High Street Honey Karly has tried on housemate Sophie's 30 GG bra to compare their breast size.

Glamour model Sophie removed her bra and gave it to the 21-year-old in front of housemate Cairon, 18.

Earlier in the week, the two girls had teased Cairon, Siavash and bisexual housemate Freddie by pretending they were lesbian porn stars.

"Sometimes we just stay in bed and have sex all day. With each other," said Sophie, 20.

Karly added: "Our porn movie was called 'She's the t***, I'm the a***'."

Sophie, who has previously appeared in Playboy magazine, has said that she would not rule out having a boob job.

The model changed her name to Dogface by deed pole upon entering the house.
