I know. There must be something in the water at the minute.

The Avatar actress tied the knot with her beau Marco Perego in London last year following a few months of dating, but she admits it took her less than a month to organise her secret big day.

Speaking to the Hollywood Reporter, she said: "As soon as we decided we were going to get married, we didn't wait. We did it three weeks later. That part was very, very quick."

The 36-year-old star - who was engaged to long-term partner Keith Britton until their split in 2011 - had previously vowed she'd never get hitched, but falling in love with Marco changed her mind. That and she's rumoured to be three months pregnant.

She explained: "I've known my partner for five years. I knew of his work. I knew of him (not quite the same thing...) Then we met. And months later, we both made the decision to do what we both individually vowed never to do - to get married."

Meanwhile, the loved-up couple are reportedly expecting their first child together and are delighted about becoming parents, but don't intend on confirming the news just yet.

A source said recently: "Zoe is about three months pregnant. But she will only announce the news when she's ready. Zoe has always wanted a big family, and Marco's on board too!"

Yeah, have the first one and then get back to me regarding the "big family."
