The 'Big Bang Theory' actress split from tennis player Ryan Sweeting in September 2015 after just 21 months of marriage and, following a "bizarre" year, things are now "much, much better".

She told talk show host Ellen DeGeneres: "Yes, I'm getting divorced. You know, last year was very bizarre and we all go through really weird ups and downs.

"And sometimes I'm a little bit more seen. And everyone goes through that stuff... You know, so I already feel like 2016 is going to be a much better year than 2015.

"And you know, it's been rough, but things are going good. I'm much, much better now. I'm in a much better place than I was."

The 30-year-old actress also admitted she had made a mistake in getting a tattoo on her back to commemorate her wedding, but showed off the artwork she's had etched on her back to conceal the original design.

She said: "I know. I know. I know. I had the date tattooed on my back and everything to remind me.

"Yeah. I know. I know. Don't tattoo wedding date. I know. I know...

"I had to cover it, I had to cover it with the wings... Because, it was big enough to cover the numbers... big wings.... It's just what I picked out when I was there."
