Kaley Cuoco opens up about secret tattoo on Ellen

Kaley Cuoco discussed her "dumb" tattoo while visiting The Ellen Show on Wednesday.

It all began when the "Big Bang Theory" star told Ellen about the tattoo her "very conservative" dad had recently gotten as a present to her mother for Mother's Day.

When asked what her mom said about the indelible gift, Cuoco said her mother was worried that the tattoo would have a bad influence on her and her sister.

However, when Ellen asked if she's ever consider getting inked, the 27-year-old actress revealed she already had.

"It's a tramp stamp. Of course." said Cuoco admitting she was only 17 when she got it. "I was trying to be cool. I know, so dumb… but, I forgot I even had it. It's way far back there. It's kinda far back. It hurts my neck now to see back there."
