The Almost Famous beauty played sexy dance instructor Cassandra, a teacher at the New York school attended by Michele's character Rachel Berry, on season four of the hit musical comedy, but gossip from the set alleged Hudson was not a fan of the 26 year old.
The unexpected rumours came as a surprise for both ladies, but Hudson made sure the young star knew how much she adored her by picking up the phone to dismiss the claims herself.
Recalling the phone call, Michele tells America's Marie Claire magazine, ""(She said), 'I just heard about that (the rumoured feud), and it f**king sucks. I want you to know I think you're amazing.'""
The touching conversation turned into a bonding moment for the co-stars and it was a call Michele will treasure for years to come.
She says, ""It was so classy of her to take a minute to (debunk it), even though we both knew it was the biggest piece of crap in the whole world. I told her, 'I love you, and I adore you. Thank you so much for creating a human moment with me.'""
Michele admits tabloid gossip is ""super-frustrating sometimes"", but she has learned to just let it go when the magazines get it really wrong.
She adds, ""Now I feel like, you can think what you want to think about me - that's OK. I have the most amazing fans, friends, and family members who have stood by me, and I know that my cast and crew really enjoy working with me. That's all that matters.""
