Nicole Kidman just shared a sweet photo of her and husband Keith Urban, but some fans were left puzzled over one minor detail.

The actress and her musician other half could be seen posing on a bench inside their garden on the grounds of their luxurious farmhouse in New South Wales, Australia.

Kidman captioned the cute shot: “It may be a Monday but we’re still kickin it’ back 🤠#MondayMood”

But, some social media users were quick to question the weird placement of Kidman’s hand on Urban’s shoulder.

One person asked: “Whose extra hand is that???” as another said: “Whose hand?? There’s an extra hand on Nicole’s shoulder,” before adding they’d zoomed in and realized it’s actually hers.

A different social media user questioned, “Extra hand??” as one said: “For a wild second I truly thought that arm on your leg was your own.”
