Kajol, who uses one name, has joined a Latin American and western dance class, choreographer Sandip Soparrkar told.
Former actress Sonali Bendre is also in the group, Soparrkar said.
"It's great fun. You should see Kajol do the cha-cha-cha, she's superb,'' he said. "But she dreads the rumba.''
Soparrkar said Kajol was also learning the waltz at the class.
"They've all joined the class for the love of dancing,'' he said.
Kajol returned to acting this year with a hit film "Fanaa'' or "Self-destruction'' following a five-year break.
