New Delhi, Sep 21 - Actress Karisma Kapur says she may make a comeback with a David Dhawan film but stayed tight-lipped on rumours about her pregnancy.

The rumour mills were abuzz that the 35-year-old is in her first trimester after she was recently noticed with a baby bump in a seven-star hotel in Mumbai.

'If something happens, everyone will come to know on its own,' Karisma told IANS.

Married to Delhi-based businessman Sanjay Kapur, Karisma has a four-year-old daughter Samaira.

She was in the capital Wednesday to kick off the 'Almonds - The All Natural Taste of a Good Life' campaign launched by the Almond Board of California.

One of the leading actresses of her time, Karisma took a sabbatical from the big screen after her marriage in 2003.

Asked how she has been keeping busy all these years, she said: 'I have been keeping pretty busy with my family. I have also done some reality shows, endorsements and promotions. So it has been a great balance for me.'

'I started when I was 15. My first movie ('Prem Qaidi') released before even my 16th birthday. Then, when I got married, I realised I had literally worked like a dog. I had worked in 82 movies and that's quite a lot. So I just enjoy the break and it's a great balance now. At least I am not running from studio to studio like a mad person,' she explained.

Post-marriage, Karisma was only been seen as a judge on the reality shows 'Nach Baliye 4' (2008) and 'Hans Baliye' (2009), apart from a cameo in Shah Rukh Khan starrer 'Om Shanti Om' (2007).

Two of her delayed films, 'Mere Jeevan Saathi' and 'Zamaanat', were released in 2006 and 2009 respectively.
