Christie Brinkley just experienced a major fashion slip up!

The 63-year-old supermodel had a wardrobe malfunction while leaving the Today Show in NYC on Wednesday, Feb. 15. The blonde beauty stunned in a tight, open-shouldered top with a multicolored mini-skirt, which perfectly showed off her lean physique. But, that wasn't the only thing she was showing off — her flesh colored bra was also visible through her shirt. Yikes!

The mom-of-three must not have noticed how revealing her outfit was before stepping out. The Michigan native is a mother to Alexa Ray Joel, 31, Jack Paris Brinkley Cook, 21, and Sailor Brinkley Cook, 18. Christie recently posed with her two daughters for the Sports Illustrated Swimsuit Issue.

"It was just such a surreal moment for me because I’ve looked up to all the SI models and my mom — they’ve always been my inspirations," Sailor said of the experience.

She added, "To be compared to my mother who has this extremely successful career under her belt when I’m just getting started? And to have people say I’m never going to have what she has or be what she is. I’m not trying to be her. But I’m fine. I don’t get hurt by this stuff."

Christie is still as beautiful as ever and it's clear by looking at her children that her model good looks are genetic!
