London, Feb 22 : Julia Roberts, who completely devoted the past year to her family life, has left Hollywood bigwigs wondering whether the actress is preparing to leave the big screen behind.

Recently, the actress admitted that she has become a stay-at-home mum and loves the experience.

"I am very fulfilled in my home life. I am a domestic artist, seriously."

She has spent the past year with her family and seems in no hurry to return to Hollywood''s gruelling demands.

The actress loves playing with her trio: four-year-old twins Phinnaeus and Hazel and Henry, 20 months, by her husband of seven years, cameraman Danny Moder.

However, now it is being wondered if the domestic life of the actress is stealing her away from the big screen.

"It''s just a matter of time before Julia Roberts is dethroned as the most powerful actress in Hollywood, " the Daily Express quoted a studio executive, as saying.

"It''s overdue. She has had a good run but her days are numbered. She''ll always be Julia Roberts but she can''t stay at the top for ever and frankly she seems happier with life as a wife and mother," she added. (ANI)
