New Delhi: Bollywood's star couple Abhishek Bachchan and Aishwarya Rai will remain occupied on their fourth wedding anniversary falling on April 20.

Abhishek says he will be busy promoting 'Dum Maaro Dum', releasing April 22, after which he will be off for a shooting schedule.

“I don't have a break at all. As soon as 'Dum Maaro Dum' releases, I will be going to Russia for shooting (Abbas-Mustan's) 'Players'. There's going to be no break for the anniversary as I am going to be thick in the middle of promotions at that time,” Abhishek said.

The 35-year-old whisked off his wife to the US for a vacation last year. In 2009, the actors took a week off from the shooting of Mani Ratnam's 'Raavan' and went for a holiday, while for their first anniversary, Abhishek was busy shooting in Miami for 'Dostana', and Aishwarya had joined him there.

The couple tied the knot in 2007 in Mumbai.
