Kelly Clarkson was so excited to meet Meryl Streep that she forgot to introduce herself

Speaking to reporters at NBC's winter press day, she said: "I don't even think she knew who I was. Then I felt horrible with Michelle Williams and the other women standing there. I was like, 'I love y'all too!'"

And Kelly had previously admitted she was left feeling "humiliated" when her over-zealous reaction - in which she screamed “Oh my god that’s Meryl!” - to meeting Meryl was shown on television.

She shared: "I was humiliated when I watched it back. I was very excited, and I hope I don’t lose that excitement, just being a true fan of people. But she’s Meryl Streep ya’ll! Everybody would’ve looked like a jacka**. She touched my face ya’ll!"

Kelly was wrapping up an interview with Ryan Seacrest when she spotted the actress, and immediately went to meet her, asking: "Can I meet you?! I’ve adored you since I was like eight."

And Kelly revealed that alongside becoming a mother to her children River, three, and Remington, 20 months - whom she has with her husband Brandon Blackstock - meeting Meryl was the "favourite moment" of her life.

She said: "Meryl Streep caressed my face on the red carpet, so that would be my favourite moment of life - other than childbirth, I'm supposed to do that."
