The star couple completed 36 years together on Friday.
Rishi took to Twitter to thank all his well wishers.
“Well, thank you all for your wishes. Just that was in the hospital for a minor procedure. Back home now tired, drained out, weary to party,” Rishi tweeted on late Friday.
Rishi and Neetu have two children together – son and actor Ranbir Kapoor and daughter Riddhima Kapoor.
Soon after Rishi’s tweet, many fans took to the micro-blogging site to wish good health to the “Bobby” star.
One fan wrote: “@chintskap Take care sir”. Another one wrote: @chintskap ‘Health is Wealth’ take care of it sir.”
Wishes also came in from his fans abroad.
One wrote: “@chintskap Stay blessed sir. Beautiful flowers for you sir. Lots of respect from Rani. Here from Denmark.”
Ace choreographer-filmmaker Farah Khan also wished “happy anniversary” to the couple.
“@chintskap n Neetuji, belated Happy Anniversary. They say marriage is a relationship where one is always right. And the other is the husband,” she tweeted.
