Vivek Oberoi celebrated his birthday on September 3.

As it was his first birthday after his marriage to Priyanka Alva, she decided to surprise her hubby by going down to Wai along with her in-laws where VO was shooting.

Priyanka called up the production guys and with their help planned a surprise bash to bring in his birthday by the poolside of the hotel where the unit is staying.

Vivek was ecstatic and stated that this was the most special birthday ever.
