The photo of Lara Bingle and her brother that has us all confused.

Would you take a photo like this with your brother?

Lara Bingle is currently holdaying in Hawaii with her boyfriend, Sam Worthington. But it looks like their party of two was crashed by Lara’s brother, Joshua.

Lara was so excited about his arrival that she took to Instagram to share a photo with him.

Lara captioned the snap with "My brother's here!!!"

In the photo she is wearing a g-string style swimming costume.

Too much nudity near a sibling? We'll let you judge for yourself.
