The Desire - Journey of a Woman actress gave birth to her first child with businessman Raj Kundra in May this year.
Speaking to IANS, the 37-year-old said: "Right now, I am a full-time mother and completely enjoying it. I have no time for films. I am on a sabbatical for I don't know how long. Motherhood is such an amazing experience that everything else takes a back seat."
The actress also commented on the pressures on women in the public eye to return to their pre-baby weight.
"There are pressures on every woman but being a celebrity when we are scrutinised every time for everything, the pressure surely increases. But I haven't started losing weight because it is not on my priority list right now," she explained.
"It is my baby and all that is important for him that tops the list. Life has changed from being a woman to a mother, but it is beautiful."
Shetty, who claimed that The Desire will be her last film role for the foreseeable future, said she does not miss acting.
Aishwarya Rai Bachchan was also the focus of intense media scrutiny for her post-pregnancy weight.
