Abhishek, who is married to actress Aishwarya Rai, has a daughter named Aaradhya. She turned one in November 2012.
He will turn up at the Beri's special show Saturday, and he will walk the ramp along with a few kids. Beri is excited.
"The Bachchans have always been generous and have done their bit for the society - be it raising charity through the sale of special paintings or attending the Silver Star charity diner in London. Moreover, Abhishek is not only an excellent actor, but he makes a great dad too," Beri told.
"With baby Aaradhya in his life, he not only relates to Baby Beri but is equally excited to be a part of this charity event. I couldn't have thought of anyone else but him as our star guest for the show," she added.
Beri also feels that "with great power, comes great responsibility". This is one reason why, she feels, celebrities can help in spreading awareness about noble causes.
"A celebrity is always under the radar of the public and we can make the most of this by spreading awareness of a cause," said the designer, who launched her first label 'Ritu Beri' in India in 1990.
Through her latest collection, she hopes to spread awareness about autism among kids.
"Autism is a complex, lifelong disability affecting a person's communicative, interpersonal behaviour, imagination and social abilities. What's heart -rending is that the awareness of autism in India remains abysmally low.
"I hope that my initiative brings a significant change in the plight of the autistic children," she said.
So what will be the theme this time?
"'The Hippie Baby' is the theme for our Baby Beri 2013 show! Fun collections of occasion wear for kids where peace, love, and freedom are the theme of the collection. Extremely colourful, the mood of this collection is absolutely carefree and crazy."
She has mixed the casual look with a little tribal feel for the kids.
"It's a myriad of designs and a plethora of vibrant colours for girls and boys. The simple and generous cuts of the dresses carry over the excitement and thrill of the look. The amalgamation of their generation with the style from the 1960s, is absolutely adorable and intriguing," she added.
