...................for stripping off in front of her husband

Trouble ... Lacey Banghard stripping off caused a huge row in the house

HEIDI Montag waged war against Lacey Banghard last night when the glamour model stripped off — in front of her husband Spencer.

But Spencer leapt to the defence of the sexy 21-year-old as she was just trying to have a SHOWER.

In scenes shown on Celebrity Big Brother on Channel 5 last night, the Hills star, 26, blasted Lacey when she shed her clothes to have a wash while married couple Heidi and Spencer — known as Speidi — were in the bathroom.

Even though Lacey was concealed by a frosted pane of glass, she said: "You're not wearing anything in there?"

To which Lacey explained: "Sometimes you forget to get your bikini and stuff, it doesn't feel normal."

Heidi and Spencer left the bathroom but Heidi warned Spencer: "Lacey's naked, we're not going back in there. That is super inappropriate!"

Nonplussed Spencer, 29, told his wife: "That's why I left, I knew how she operates. A 20-year-old naked model... it's nothing to her."

And Heidi raged: "I don't really care but I don't want to be around it.

"Do what you want to do, but not around me and my husband. That's fighting talk where I come from."

But her husband, unperturbed by Lacey's naked body behind the frosted glass, told Heidi: "It's not as if she actually got naked in the bathroom."

Lacey eventually came back into the bedroom and was comforted by Claire Richards and Tricia Penrose.

She said to them: "How do you guys wash? It's normal isn't it."

Heidi and Spencer went into the bathroom and she turned to her husband and told him: "I need to get out of here, no sane person should be living like this."

Spencer said: "If it was a clear shower, maybe it's a big deal. I'm sure other people are showering naked."
