Bollywood stars Abhishek Bachchan and Aishwarya, who tied the nuptial knot yesterday, are likely to leave for Venice in a couple of days for their honeymoon.

A huge reception is also likely to be held in early June, according to sources.

Soon after the wedding, the couple is supposed to have visited the Lilavati Hospital where the matriarch of the Bachchan family, Teji Bachchan, is recuperating. Now with Aishwarya entering the Bachchan family-fold, the Bachchan brand value has now soared much above the Rs 700-crore mark.

According to financial analysts and trade experts, the Bachchan brand value is worth Rs 700 crore as Amitabh and Abhishek are brand ambassadors for various products. Aishwarya, becoming a part of the family now, could add to that value by several crores.

Among the filmstars who endorse products, Amitabh Bachchan, Aamir Khan and Shah Rukh Khan are the highest paid stars who charge between Rs four crore to Rs five crore for a single brand.

Aishwarya, who was chosen by the TIME magazine's Asia's edition as one of Asia's ''100 most influential People'', is the brand ambassador for prestigious products such as L'oreal, Nakshatra Diamonds and Lux, to name a few.

Amitabh Bachchan endorses products such as Reid & Taylor, ICICI Bank, Nerolac, Dabur India, Pepsi, Parker Pens and Cadbury choclates. While Abhishek endorses Ford Fiesta, Omega, Radio Big 92.7 FM, Motorola, LG Home Appliances, and American Express, among others.

The Big B charges upto Rs 5 crore per ad, followed by Aishwarya who charges Rs 3 crore per ad while Abhishek is not far behind.

Abhishek's brand value has recently gone up after given hit films like Mani Ratnam's 'Guru' and 'Bunty aur Babli'.

The three stars have their own clientele and cashing in on the marriage, L'Oreal has introduced a limited edition lipstick shade under its Colour Riche range, Tender Beige for their brand ambassador Ash.

''This is the first time we have done something like this. We have never done this before,'' says a spokesperson for L'Oreal. The lipstick will be launched later in all the metros of India.

The more the Bachchans keep the marriage details a secret, the more people are going crazy. Brands are falling over each other to get the elusive Bachchans together.

Some of the other cricketers / filmstars who have their own successful brands include Kajol and Ajay Devgan, M S Dhoni, Sachin Tendulkar, Rahul Dravid and Akshay Kumar to name a few. Ad man Prahlad Kakkar who was the first person to launch Ash in the famous Pepsi ad with Aamir Khan and Mahima Choudhry is esctatic about the marriage.

The Bachchans have a huge fan following and whatever they do, their fans emulate them. The products endorsed by them will be purchased by fans, he says.

According to the trend today, filmstar marriages not only have entertainment value but are profitable business ventures worth several crores. The case in point being the recent Liz Hurley-Arun Nayar wedding held in Jaipur, the rights of which were sold to Hello! Magazine for one million pounds.

But amidst all this the Bachchans are the beneficiaries who will be laughing all the way to the bank.
