Hedge fund manager James popped the question to Kate Middleton's younger sister Pippa on Sunday (17 July), presenting her with a gorgeous diamond ring estimated to cost around half a million pounds.
Speaking on today's Loose Women, Vicky joked: "I dropped the ball, haven't I? She has a £250,000 engagement ring. Of course I'm gutted!"
Vicky briefly dated James' younger brother Spencer after they met in the I'm A Celebrity... Get Me Out Of Here! jungle before Christmas, but things fizzled out and he's now dating model Morgane Robert.
When asked if Spencer would be able to give his future wife a £250,000 ring, Vicky said: "I have no doubt Spencer would be able to keep whoever he is with in a high style! Unfortunately it wasn't me! He has moved on, has a lovely new girlfriend, and I'm very happy for him."
She then quipped: "It pains me to say!"
The panel also discussed Pippa's huge diamond ring, with Janet Street Porter saying she felt engagement rings were outdated and she didn't like photos of celebrities holding their hands at awkward angles just to flaunt the ring.
But Vicky disagreed, saying: "This is a woman who is engaged for the first time. She's seen her sister have this great romantic big fairytale, she's in love, happy, she has a big sparkler on her finger, she's engaged to someone gorgeous. Why shouldn't she flaunt it?"
