New Delhi: Actress Aishwarya Rai is down with a "chest infection" and "flu-like symptoms" and her father-in-law, Bollywood megastar Amitabh Bachchan, is worried.

"Aishwarya has taken ill and is down with chest infection and flu like symptoms. She had a high fever yesterday, but is settling down today," he posted on his blog Saturday from Singapore.

"It's worrying to be so far away from children and not be there to look after them. Yes, they are mature and married and responsible, but children will always remain children," he added. Aishwarya is married to Bachchan's son Abhishek.

The 66-year-old veteran is in Singapore to look after his friend and Samajwadi Party chief Amar Singh, who underwent medical treatment there.

"I stay back till he (Amar Singh) is sound enough to travel back," he wrote.

Apparently Bachchan also is suffering from a "strained back".
