LOS ANGELES:

Jared Leto has told Sienna Miller she can lose weight on a diet of curry powder and “lots of sex”.

Sienna was forced to pile on the pounds for her role in new film Hippie Hippie Shake, and the Fight Club star has recommended his unique we-ight-loss technique as a gr-eat way to slim back down.

A source told Britain’s Daily Express newspaper, “He can lose 14 pounds in a month on an all-liquid diet by mixing water with curry powder |or pepper and combining it with lots of sex. Apparently Sienna was amused by his advice as she has had to put seven pounds in the past few weeks for her role as a flower child in the film Hippie Hippie Shake.”
