After her arrival from Bangkok, actress Katrina Kaif reportedly visited her alleged beau Ranbir Kapoor's house to check on his father, actor Rishi Kapoor, who is down with malaria and dengue. The actors were shooting for Anurag Basu's Jagga Jasoos in Thailand. Katrina and Ranbir returned to Mumbai on Tuesday night and the actress drove straight to Krishna Raj (the Kapoors' bungalow in Bandra) to meet Rishi Kapoor.
