Kaley Cuoco: Covers Up Failed Marriage ... With New Ink

Kaley Cuoco opted for another tattoo instead of laser removal when getting the giant reminder of her soon-to-be ex-husband Ryan Sweeting removed from her back.

Cuoco had the giant Roman numerals of their wedding date covered up with what looks like a giant butterfly tattoo. She posted a pic of the finished ink and she said there was no real meaning to the design ... but she seems to be experiencing some kind of metamorphosis.

We're told Cuoco came into the tattoo parlor Tuesday on a whim and was there for about an hour getting the ink.

She paid about $150 for it ... probably a lot less than the checks she'll be paying Sweeting once the divorce is finalized.
