Pregnant Lara Worthington Just Wore $5,000 Pyjamas On The Red Carpet

When you're pregnant it's all about being comfortable.

Appearing at Louis Vuitton's reopening of their flagship store in on George Street in Sydney, Lara Worthington was hiding a surprise under her fancy pyjamas.

The model announced she is pregnant with her third child during her appearance on Wednesday night.

“I’m having a boy, early next year. It’s my third boy, and we’re all very excited and very happy," she told Vogue Magazine.

"I think any addition brings joy and happiness to the family, but more so when you can share it with the other boys. It’s such a boys' club in my house!”

Worthington wore the Louis Vuitton monogram shadow pyjama top ($2490) and matching pyjama pants ($2300), pairing her super fancy pjs with black heals.

With no bedhead in sight, her hair was pulled back in a tight sleek bun and she wore a pop of red lipstick with minimal makeup. And it's the most stylish sleep time outfit we've ever seen.

Worthington walked down the 14-metre long black carpet with a slew of other celebrities, including Elsa Pataky, Kate Waterhouse and Georgia Fowler, as well as fashion-lover Julie Bishop.

Just like Worthington, many other guests at the event were decked out in head to toe Louis Vuitton outfits and carrying the designer's handbags.

Worthington is already mum to Rocket Zoe (born in 2015) and Racer (born in 2016) who she shares with husband Sam Worthington.

We're taking guesses on which 'R' themed name the pair will choose for their third baby boy.
