According to the Daily Star, Miss Wales Stephanie Holland and Miss Scotland runner-up Karly Ashworth will enter the house during the series.
22-year-old Stephanie is apparently a "trained pole dancer" who is planning to use "her ample assets" to increase her chances of winning.
Meanwhile, Karly from Fife apparently has 34B breasts and "loves stripping off".
A source commented: "It's going to be a real battle of the hotties. Karly’s due to go in first. She'll certainly have time to get the fellas in the house all steamed up.
"She will think she's Queen Bee or Queen BB. But as usual with Big Brother, they will shake things up. They plan to throw Stephanie in which will ruffle Karly’s feathers."
The tabloid report also claims that this year's lineup includes a "Brazilian lad", a "wannabe from Pakistan" and a "cheeky joker" from Ireland.
Big Brother 10 starts at 9pm on Channel 4 on Thursday, June 4.
