Comedian Celeste Barber suffered an embarrassing photo blunder as she posed with actress and Sean Penn's ex-wife Leila George at the Australian Open last week. 

The 40-year-old posted a photo to her Instagram story cosying up with the star, however she didn't realise that her over-the-shoulder bag was in a questionable position.  

Captioning the hilarious photo, the comedian wrote: 'Note to self when you're having a photo with Leila George unhook your bag from around your boob.' 

The two were pictured together inside the Ralph Lauren suite at the Rod Laver arena at the Australian Open finals.

Despite the photo blunder, Celeste looked stunning in a mid-length khaki shirt-dress as she wore her brunette hair tied in a bun and she completed her look with trendy white sneakers and statement gold jewellery.  

Leila was also looking stylish as she donned a navy bandana-style top and yellow suit trousers. 

The comedian was spotted spending most of her time at the finals party with her husband Api Robin, who cut a dashing figure in a crisp white dress shirt and tan trousers.

The lovebirds were all smiles as they embraced and posed up a storm together in the Ralph Lauren suite. 

The mother-of-four told her 9.4million Instagram followers that her husband was left stunned when he saw an amazing photo of them together on the night. 

'He said "Holy s**t" when I showed him this photo,' she wrote next to the snap. 

It comes after Celeste addressed the backlash over her parody of Emily Ratajkowski's G-string-clad photo shoot, saying she has no regrets about posting the video. 

The comedian landed in hot water last year after the American model, 31, blocked her on Instagram after she mocked a photo of Ratajkowski seductively leaning against a wall in nothing but a pair of tiny bikini bottoms.

But, the Aussie funnywoman told this month's Marie Claire that she didn't mind the criticism.

'I like running my mouth off. I do it a lot. I'm quick-witted – it's one of my favourite things about me,' she told the magazine.

'I don't like that I feel I can't do that as much, and I censor myself sometimes. You can't win. They hate what you do one day, then you're the greatest thing in the world the next day.'
