The star sister was seen exiting the building along with her hubby, Aayush Sharma.
Arpita Khan and hubby Aayush Sharma were among the list of family and friends, who visited Salman Khan after his acquittal in the 2002-hit-and-run case.
This is the first time that Arpita has been snapped by the paparazzi with her baby belly.
Buzz about her pregnancy had started doing the rounds during Ganpati festival, but the Khans, after an initial confirmation, chose to keep mum about it.
Arpita Khan wed longtime partner Aayush Sharma in November last year at the Falaknuma Palace in Hyderabad in a grand wedding ceremony, which was attended by the who's who of Bollywood.
The wedding festivities were followed by a lavish reception hosted by Salman Khan at Taj Land's End, Bandra.
Arpita Khan celebrated her birthday with a star-studded bash hosted by brother Salman at his residence in August and both Arpita and Aayush later took off to a trip to Barcelona with other family members.
