Bollywood actress Shilpa Shetty says her son, who was taken ill last week, is fine now and that "the worst is over".

"(I have) been in the hospital since Sunday evening, my son Viaan has been very ill. He is better now. A distressing time for us all. The worst is over," the 37-year-old tweeted.

Shilpa, who married London-based Raj Kundra in 2009, gave birth to her first child in May last year.

Currently seen as one of the judges on the fifth season of "Nach Baliye", the actress "skipped" shooting for the dance reality show.

"Had to skip 'Nach Baliye' shoot today (Tuesday), just couldn't do it. Grateful to Star Plus for understanding my predicament. Thank you all for your good wishes," she further tweeted.
