Ever since Aishwarya Rai married Abhishek Bachchan last weekend, all have pondered and speculated what surname she would choose to use.

Well, wonder no more...reports are that Ash has decided.

The newest member of the Bachchan household will take her new husband's name - becoming Aishwarya Bachchan, said her father-in-law, Amitabh Bachchan.

As a matter of fact, Ash has already signed an autograph as Aishwarya Bachchan, Big B said in an interview to a daily published on Thursday.

"She desires to use Bachchan as her surname," Bachchan said.

Bachchan also stated that the new couple would move in with him and his wife rather than a home of their own.

"This decision came voluntarily from Abhishek and Aishwarya," Bachchan said.

As for his daughter-in-law's film career, Bachchan expressed that he hopes she'll continue acting.

"Jaya and I have insisted that Aishwarya must continue with her acting career," Bachchan said. "There is no problem or issue with us."

Bachchan also denied reports that photos or film footage of the wedding have been sold to anyone.

"No such offer has come and even if it did, we would reject it," Bachchan said.
