Victoria Beckham got candid about a certain look with husband David Beckham that still "haunts" her to this day.

On Monday's episode of "Watch What Happens Live," the singer-turned-designer opened up to host Andy Cohen about an outfit she's still embarrassed by — the matching black leather pantsuits Beckham and her husband wore for their Millennium New Year's Eve Party in 1999.

"I still ... I mean it haunts me," she told Cohen. "It does haunt me, but I love it. But, you know, we really considered those outfits. I mean we really talked about it. There was a naivete to it that was just so sweet."

When Cohen asked why it still haunts her, Beckham replied, "Because everybody pulls it out of the bag."

Beckham also addressed whether she'd be up for a Spice Girls reunion after a fan had asked her.

"You know, I had so much fun being in the Spice Girls, but, you know, I think that now with everything else that I've got going on with my fashion and my beauty line, four children, you know, I just — I couldn't commit to that," she revealed.
