It's been an up and down time for Bollywood mega star Aishwarya Rai lately — weight wise, that is.

Her directors, not satisfied with having Bollywood's leading lady in their films, have made her lose weight, gain weight and lose it again for successive films, the Times of India newspaper reported Thursday.

Most recently Rai, a former Miss World often labeled as one of the world's most beautiful women, was asked to shed a few pounds for her role in the film "Dhoom 2," or "Big Bang 2," which is being shot in Namibia, the paper reported.

Rai's personal trainer Deepika is on sight leading "Ash," as she is known in Bollywood, through a two-hour workout starting at 4 a.m. every morning, the paper said.

"Deepika is with Ash in Namibia," Rai's manager Hari Singh told the newspaper. "Ash is a very dedicated actress and she is working to get into the skin of her role."

Rai had picked up some extra pounds for her role in the film "Guru," which she was filming before heading to Namibia for Dhoom 2.
