Margot Robbie has adopted a dog.

The 'Suicide Squad' actress and her husband Tom Ackerley only got married last December in a secret ceremony in Australia but have been quick to take on some extra responsibility, giving an adorable ''rescue pup'' a home.

Margot revealed her new mutt mate in a post on her Instagram page of a black and white photo of the cute canine accompanied with the caption: ''Our little rescue pup, Boo Radley.''

It's not yet clear where Margot and Tom drew inspiration for the name, but fans have started to speculate that the pooch is named after the reclusive character Arthur ''Boo'' Radley from the 1960 Pulitzer Prize-winning novel 'To Kill A Mockingbird' written by Harper Lee.

Boo is well known character that never sets foot outside his house - a possible nod at the characteristics of her pooch.

Alternatively, the other famous Boo Radley is the British 90s rock band The Boo Radleys - who had a top 10 single in 1995 with 'Wake Up Boo!'

Margot, 26, has been busy filming Tonya Harding biopic 'I, Tonya' in Atlanta, Georgia, along with Caitlin Carver who portrays the disgraced ice skater's rival Nancy Kerrigan.
