The 29-year-old actress appeared on The Tonight Show With Jay Leno on Thursday, Nov. 14, and answered some probing questions about her ultra-revealing black Azzaro Couture dress.
"How does that even stay on?" Jay Leno asked the brunette beauty.
"Well, there was a lot of toupee tape," Alexander responded.
Okay, but was Alexander completely naked under the very sheer gown?
"Did you wear anything under that dress?" the late night host inquired. "Well, like underwear or something like that?"
"There was something under there," Alexander simply responded, without going into much detail.
Perhaps that "something" was underwear? We might never know the answer.
As for moving around in the sexy number, Alexander said it required "flexing every muscle that I don't have."
All eyes were on Peter Facinelli's ladylove at the premiere on Monday, Nov. 4, as the actress walked the red carpet at the El Capitan Theatre in Hollywood. The look left little to the imagination, as it featured a see-through center panel in the front and back.
Alexander and her stylist, Emilie Pereira, knew how daring the dress would be "but this one was a fashion risk she felt worth taking," Alexander's rep told E! News on Tuesday, Nov. 5.
"Jaimie, Emilie and her seamstress were meticulous to ensure that proper measures were taken to so that there were no wardrobe malfunctions," the rep explained. "Jaimie felt extremely confident in the gown or we would have gone in another direction."
