She may have kept the news of her marriage under wraps for the first ten months.

But Lara Worthington couldn't help but share her excitement as she and husband Sam celebrated their first wedding anniversary by posting a throwback snap.

Using social media to express just how blessed she feels, the model and mother-of-one shared a rare selfie of the happy couple to her Instagram page on Wednesday and wrote: 'Still can't believe how lucky I am'.

Lara, 28, is seen leaning her head against Sam's in the sweet black and white image shared along with the hashtags, '#oneyearagoyesterday', '#28.12.2014' and '#married'.

The photo appears to have been taken some time ago however, as the blonde's hair is still styled in a tousled bob rather than her new pixie cut.

Sam, who rarely features on her social media accounts after he deleted his own last year, appears shirtless by her side while their nine-month-old son Rocket Zot isn't pictured.

Lara and Sam, 39, married in an intimate Melbourne ceremony with less than ten guests in attendance.

She was six months pregnant at the time and told KIISFM in October that it was a very personal affair.

'We wrote the whole celebration, we wrote all our vows,' she said, before adding that the meal after the ceremony was prepared by herself and her mother.

Lara's wedding day look was a relaxed one, with the beauty saying: 'It was super chilled. Just before the wedding I was in London, it was really cold at the time and finding a dress at six-months-pregnant (was difficult).'

'I found something at Louis Vuitton, it was white.'

Lara changed her surname to 'Worthington' on social media after they said their vows but didn't confirm that they had wed until just two months ago.

She began dating Sam in September 2013 and the couple welcomed their first child together in March this year.

Reflecting on motherhood, Lara told Daily Mail Australia recently: 'It's the best thing in the world.'

'It's definitely something new. It's very challenging, and I'm learning something new every day which is awesome.'
