Kaley Cuoco has apologised for posting a picture on social media on Independence Day of her dogs sitting on an American flag.
Commenters sharply criticised the Instagram photo, which the Big Bang Theory star had said was taken by her dog sitter while she was out of town.
She later removed the picture and posted another with a graphic of an American flag in the shape of a heart.
She wrote: "I would like to comment on a photo I posted yesterday, that has caused lots of controversy. First off, please know, I have the utmost respect for my country. I am a proud American in every sense of the word. I understand the American flag stands for our freedom and represents American heroes, past and present.
"Yesterday I made a mistake by posting the picture that was taken of my sweet dogs posing on an American flag. I sincerely apologise to anyone that has been offended by my previous post.
"This is no way reflects my feelings toward what the American flag represents. Living in the public eye, can be extremely difficult at times. Every mistake and every imperfection is amplified. I am not perfect."
She ended her message saying she was a "proud American, today, tomorrow, always".
