In 2010, Kapoor reteamed with Ken Ghosh in Chance Pe Dance, a comedy-drama about a struggling actor, in which Kapoor's performance was described as "uneven" by Aniruddha Guha of Daily News and Analysis. He had a supporting role in Paathshaala, a drama about the education system in India, starring Nana Patekar, following which he starred in Yash Raj Films' Badmaash Company, a comedy-drama about a group of overambitious youngsters who become con men. Rachel Saltz of The New York Times praised Kapoor's look in the film, though Tushar Joshi of Mid Day thought that he was miscast. Kapoor's fourth and final release that year was Satish Kaushik's romantic comedy Milenge Milenge, which marked his fourth collaboration with Kareena Kapoor. Plagiarised from the Hollywood film Serendipity, the production was delayed since 2005. During its production in December 2004 at Phuket, Kapoor requested a delay in filming to attend the premiere of Dil Maange More. The delay may have saved the lives of the crew, since the hotel booked for them was destroyed during the 2004 Indian Ocean tsunami. With the exception of Badmaash Company, none of these films performed well commercially.
Kapoor practices vegetarianism, and credits the author Brian Hines' book Life is Fair for influencing this lifestyle choice. He also supports charitable organisations for various causes. In 2010, he took part in a charity event named Superstars Ka Jalwa, which helped generate money for the employees of the Cine and Television Artists Association (CINTAA). Also that year, he lent his support to the NGO Swayamsiddh, which helps children with special needs. The following year, he adopted three villages in support of NDTV's Greenathon, an initiative to support environmental consciousness and improve electricity supplies to rural areas. In 2012, Kapoor helped revive the Victory Arts Foundation NGO, founded by Shiamak Davar, which helps underprivileged children through dance therapy programs. Also that year, he appeared alongside other Bollywood celebrities in Because My World Is Not The Same, a short film by Zoya Akhtar, to generate awareness on breast cancer. He supports the People for the Ethical Treatment of Animals organisation through advertisement campaigns.
