She carried a brown leather satchel as a crossbody bag and a bright red leash to match the Great Dane’s collar, which stood out against his black and white fur.

She showcased her radiant beauty and flawless skin in light and rosy makeup.

Her new movie The Friend is based on Sigrid Nunez’s 2018 same-name novel about a woman and her bond with her dog.

‘I have a dog that is six pounds,’ she told the talk show host. ‘This dog is 150 pounds I believe. And it’s my co-star. He really is gigantic.’

She gushed about the opportunity to play opposite an animal in a leading role on the movie and said Bing is ‘very lovable’.

‘It’s not often that a dog has the starring role,’ she said. ‘He’s a special dog. Very lovable. He’s a good dog.’

She also opened up about what it takes to act alongside a dog and explained they work with a trainer very frequently while shooting.

‘I have to have all kinds of doggy trainings,’ she explained. ‘You know, every 20 minutes, we have to go through all of these — these tricks. He can do a lot of things.’
