But we can (and will) make some guesses based on what she did say.
It looks like we can trust VB with our secrets.
Victoria Beckham appeared on The Late Late Show with James Corden alongside Shaquille O'Neal to promote her collaboration with Reebok last night. Naturally, Corden had to ask her about the upcoming royal wedding, you know, Brit to Brit. But, like a good friend, the fashion designer denied she was creating Meghan Markle's dress and refused to confirm any details.
Beckham also played coy about whether she'd be at the May wedding, causing Corden to call her out on her ability to fib. "That was the biggest yes I've heard in my life," the host laughed.
In Beckham's defence, it was already expected that she and husband David would be in attendance since they were at Prince William and Kate's wedding in 2011.
Check out what she has to say about the big day, starting around the 1:23-minute mark.
