New Delhi: The most talked about couple in Bollywood, Abhishek Bachchan and Aishwarya Rai, tied the knot four years ago amid media frenzy, but Big B feels 'it all happened a few hours ago'.

'It's Abhishek and Aishwarya's wedding anniversary today the 20th of April and have wished them before they turned in. Cannot imagine its been four years! All the excitement and the marriage details, family and relatives in and around a packed house, preparations, customs, rituals ... seems just like it all happened a few hours ago,' Amitabh posted on his blog www.bigb.bigadda.com.

Unlike all their previous anniversaries when they were abroad, Abhishek and Aishwarya are in Mumbai this time for their special day. Abhishek's involvement in promoting his upcoming film 'Dum Maaro Dum' has kept them away from holidaying.

Some friends from the film industry also took to social networking site Twitter to wish the duo.

'Wishing @juniorbachchan and Aishwarya a very very Happy Anniversary. Lots of love,' posted southern actor Rana Daggubati, who is making his Bollywood debut with 'Dum Maaro Dum'.

Actor Viveck Vaswani posted: 'happy happy anniversary Abhishek and Aishwarya and god bless you both always.'
