Riteish was spotted leaving alone on Tuesday for the event. Rumours say Genelia is pregnant and that's why she preferred staying home.
Her being pregnant was talked about earlier this month, but since then she hasn't given out any confirmation or denial, unlike Vidya Balan who promptly denied rumours about her impending pregnancy.

Honey Bhagnani, who is married to Riteish Deshmukh's younger brother Dheeraj is also pregnant. Vashu Bhagnani's daughter was recently spotted at a film screening with a baby bump.
Interestingly, Genelia and Riteish and Honey and Dheeraj got married in the same month - February - in 2012.
