The US X Factor star chose a floor-length velvet wrap gown, which was tied at the waist with a thin belt.
But, it seems it wasn't secure enough as Stacy revealed to the crowd that she had seemingly opted to go knickerless for the occasion.
Her dress fell out of place as she posed up a storm for the cameras waiting for her outside the Borehamwood Bungalow.

The singer chose a risky green wrap dress for her eviction
And, it wasn't just her modesty that she flashed. The 47-year-old's ample assets also risked spilling out of her plunging look.
Her generous cleavage took centre-stage during her interview with host Emma Willis, as the halter-neck style number struggled to hold everything in place.
It wasn't until she sat down to discuss her time in the house that Stacy became aware of just how risky her dress was.
She could be seen clutching at the skirt of her gown as she held it in place as she opened up about her experience on the Channel 5 reality show.

Stacy asked Emma is Kim Woodburn was senile
Stacy, who is the sixth housemate to be evicted, certainly didn't hold back in her interview with Emma as she branded Kim Woodburn "senile".
She told the brunette beauty: "Is Kim senile? We did a task yesterday and Kim just never got it, she's 75 years old now and I think she just doesn't care?"
The singer added she thinks overall the How Clean Is Your House? star is "a good person" but, she'd like to see James Cosmo win the series.
Celebrity Big Brother continues tomorrow on Channel 5 at 9pm.
