LACEY Banghard stripped off in the Celebrity Big Brother house - despite only being in there for 24 hours.

The 2010 Page 3 Idol winner braved the January temps to enjoy a dip in the hot tub.

But there was no sign of a skimpy bikini as the 26GG beauty took to the water in a strappy, low-cut pink top and grey knickers.

The 20-year-old had already whipped her skirt off while lounging in the igloo with Tricia Penrose, Frankie Dettori, Gillian Taylforth, Rylan Clark and Claire Richards.

She pranced about with a bottle of champagne wearing an appropriate lacy top and huge Bridget Jones-style knickers.

Page 3 beauty Lacey Banghard wore a cut-out gold shimmery swimsuit as she took to the tub last night. While Tricia Penrose opted for a black halterneck costume.

Former Heartbeat star Tricia was then seen quizzing Lacey on what size her famous assets were.

Lacey, 21, replied: "About 28G, but I don't think they're that big."

Tricia also asked if they were real. And Lacey, who was seen giving her boobs a fondle, added: "Yeah, feel, completely real."

Tricia then gave them a little squeeze too.

Later, Lacey was chatting to Heidi Montag and got some love tips.

Heidi told 20-year-old Lacey: "There’s such a great guy out there for you who will worship you."

Lacey replied: "I hope so…I might end up like Paula! I want kids."

On entering the house last week, Lacey won the best dressed celeb award, which is ironic really as she has said she is most comfortable in her underwear!
