We know that Heidi Montag is a bit possessive of her husband Spencer Pratt, but her outburst on last night's Celebrity Big Brother took things to a whole new level.

Lacey was completely naked as she stepped into the shower, but in her defence she was covered mostly by the frosted door.
Heidi ranted: "You're not wearing anything in there?"
Lacey replied: "Sometimes you forget to get your bikini and stuff, it doesn't feel normal."
Spencer Pratt just seemed to find the whole thing amusing. Copyright [Channel 5]However, Heidi wasted no time in telling Spencer that they would not be returning to the bathroom whilst Lacey was starkers.
The Hills star said: "Lacey's naked, we're not going back in there. That is super inappropriate. 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."
Spencer, who was smirking, then began to defend Lacey Banghard, saying: "It's not as if she actually got naked in the bathroom. If it was a clear shower, maybe it's a big deal. I'm sure other people are showering naked."
We're a bit concerned we're actually siding with Spencer on this one.
Heidi Montag's tirade didn't end there, though. She continued: "I need to get out of here, no sane person should be living like this.'"
