Actress Anushka Sharma has become a fan of her counterpart Katrina Kaif's fitness after watching the latter's newly launched song 'Pashima' from "Fitoor".

The sensuous number "Pashmina", second song from the Abhishek Kapoor-directed film, sees Katrina performing a contemporary dance with co-star Aditya Roy Kapur.

"How hot and fit is #Katrina in the new #Fitoor song. Nailed the dance! Lovin it," Anushka posted on Twitter.

Pashmina, which hit the web yesterday, has been sung and composed by Amit Trivedi while Swanand Kirkire has penned the lyrics.

In "Fitoor", an adaptation of Charles Dickens' classic novel "Great Expectations", Aditya plays Noor, who is in love with Firdaus (Katrina). The film is slated for a February 12 release.
