Today's a big day for these famous and filmy brothers. Happy Rakhi! The Khans: Salman, Arbaaz, Sohail Stepsisters Alvira and Arpita Khan have three stalwart brothers to take care of them. The Khandaan is famously close knit. Alvira and three brothers share the same mother, Salim's Khan's first wife Salma. Arpita was adopted by Salim Khan and second wife Helen. But she's the baby of the family and, as such, pampered by everybody else.
