Raj's sister, played by Aarti Mann. Priya first met the guys in April of 2005. Raj introduced them to his sister at Bob's Big Boy in Toluca Lake, after which Leonard and Howard made a pinky swear pact not to hit on her out of respect for their friend. Shortly thereafter, Leonard slept with Priya and since then, whenever she's come to town, they've "had fun together". When she was in town in October of 2010 Leonard suggested that he might move to India so they could see each other more seriously, but she turned him down (0406). They now have rekindled their relationship (0416), and Penny has shown jealousy towards Priya.
