THEY thought it was a birthday party but when guests arrived they realised they had actually been invited to a surprise wedding.
Danielle and Andrew Karlsen tied the knot on Saturday at a low key gathering in the Danielle's mum's garden.
Today is her birthday and because the pair didn't want to make a fuss, Danielle sent out invitations saying the party would be one not to miss because the pair had "important news".
"I think some people had figured it out from the invitation," Mrs Karlsen, who is also six months pregnant, said.
"I know some of my friends thought we would be announcing the sex of our next baby, so there were definitely a few surprised faces when I walked out in a wedding dress."
Mrs Karlsen had never wanted to get married while she was pregnant, but changed her mind.
"I wanted us to all have the same name when he was born," she said.
"My ankles and fingers are so swollen my wedding ring barely fits."
She said walking out - in her flat shoes to avoid any accidental, embarrassing tripping - and seeing the look on her partner's face was the most memorable moment of the quaint ceremony.
"He looked nervous and a bit teary. I was nervous too, my lips were shaking.
"Afterwards Andrew's best man told me just how nervous he was."
The newlyweds haven't organised a honeymoon yet; instead waiting until after baby number two has arrived.
