The 48-year-old actress is close friends with her 'Money Monster' co-star but admits it can be annoying spending time with him because he is "enormously popular" and so many people want to chat with him.

She admitted: "We did go out to dinner [after filming]. George is so enormously popular that I don't always enjoy going out to dinner with him. Because everybody wants to talk to George."

And Julia - who has children Hazel and Phinnaeus, 10, and Henry, eight, with husband Daniel Moder - admitted she can't keep up the pace when out with the Hollywood hunk, leading him to brand her a "quitter".

She told TV host Ellen DeGeneres: "I have a tendency when a bunch of us go out to dinner to go home early.

"I also like to go to bed early. And he always shouts 'Quitter' as I am leaving the restaurant."

During the interview, Julia and Ellen bonded over their mutual friend Taylor Swift and shared experience of dancing on stage with her during her '1989' tour.

The Oscar-winning actress had attended the show because her kids are such big fans of the 'Shake It Off' singer.

She said: "They all love Taylor Swift and she is just number one in our house and that was their first concert ever and we took a bunch of friends and had a great time."

And Julia admitted she had been reluctant to join the 26-year-old pop star on stage in Santa Clara, California, last August.

She added: "I will say this, when she very sweetly asked if I would go on stage, my oldest son said, because I of course went 'Ugh' my oldest son said 'Mommy, you have to do it' and my youngest son said 'Mommy only do it if you feel comfortable'. "
