'Big Bang Theory' actress Kaley Cuoco received some criticism during the national holiday of Independence Day when she uploaded a picture of her dogs sitting on the US flag to Instagram. She recently apologized to the public by uploading a picture of the flag shaped into a heart, with the caption, "Living in the public eye, can be extremely difficult at times. Every mistake and every imperfection is amplified. I am not perfect. I am a proud American, today, tomorrow, always."
