Pitt, who has been the focus of much media speculation regarding his own wedding to Angelina Jolie, said that he is "glad" they will be marrying soon.
"I am glad they will soon be getting married and I wish them all the luck and a beautiful life ahead," The Hindustan Times quotes him as saying.
When asked if he felt that the Bollywood star couple were the Indian equivalent to him and Jolie, the Killing Them Softly star said: "Well, they are a good looking couple! No two individuals in a relationship can be the same as another so I don't know if it is correct to compare them to us."
Khan and Kapoor's forthcoming nuptials have been the focus of intense media speculation - so much so that the Heroine actress recently said she was certain even President Barack Obama knew of her wedding plans.
A 'save-the-date' invitation for the couple's wedding reception was recently leaked on the internet. The wedding date is believed to have been confirmed as October 16.
Kapoor has said that she intends to change her name to Kareena Kapoor Khan after her marriage.
