Now that's how you keep a pregnancy quiet.
Supermodel Erin O'Connor debuted her neat baby bump on the red carpet last night, but the true shocker is that no one knew she was having a baby.
The mentor on The Face managed to keep her bump under wraps for several months, from the looks of things.
She stunned in a vintage style black gown with her hair elegantly slicked to one side as she tenderly cradled her belly.
But Erin has never publicly named her partner, although she isn't shy about gushing about him in interviews.
"He’s funny and interesting and wears a suit every day to work, which seems so exotic and outlandish to me that ironically it makes him my equivalent of wild rock’n’roll," she told You Magazine.
"He’s also easy to love and I hope we’ll have a baby – lots of them, if we’re lucky – together. It’s a nice feeling to have found The One at long last."
"We have half a dozen godchildren between us, so I like to think we have some idea of what’s required for parenthood."
The Saturdays' Mollie King and Vanessa White were also spotted at the bash.
