'Big Bang Theory' star Mayim Bialik says her two sons Miles, 8, and Frederick, 5, are yet to know that their mother works in showbiz.
The 38-year-old actress is best known for playing Amy Farrah Fowler in the comedy series, reported People magazine.
"They don't really know who momma is. My older son knows that people come up to me and say, 'Big bang, big bang,' and want to take pictures. But to them, they know me as the person who cleans the toilets and makes their breakfast," Bialik said.
Bialik, who finalised her divorce from Michael Stone in 2013, said they discuss other things than her career when she spends time with her sons.
"I don't have a TV, I don't show them movies. I'm sharing custody, so when I see them I don't really want to put them in front of a TV," she said.
