Tamara Padi, 43, was found critically injured at an address in Lake Road, Stalybridge, having been stabbed “multiple times” inside the property, police said.
Police were called around 3.40am on Wednesday (7 July) by paramedics requesting assistance at the Greater Manchester property.
She was rushed to hospital in the early hours of Wednesday (7 July), but tragically died a short time later.
A spokesman for the force said a man was later arrested in the Dukinfield area on suspicion of murder. He is being questioned by detectives, police said.
In a heartbreaking tribute, Tamara's daughters Mia and Tia described her as “such a happy and outgoing soul” who loved them “wholeheartedly”.
Tia said: "It all still feels so surreal when I woke up to this today, it just didn’t feel the same knowing you weren’t here, knowing that the most important woman in my life is no longer here with me.
"I not only lost my mum but also my best friend all at once.
"You always were such a happy and outgoing soul, you always knew how to put a smile on my face by just being your crazy happy self.
"I hope you know that you were and still are loved by everyone and I will make sure to take good care of Mia for you. I love you."
Mia said: "Tamara Padi was my mum and my friend.
"She was always there for me and loved me wholeheartedly.
"She said that she loved how I could comfort her in the most hopeless of situations.
"She promised that I would never have a reason to cry. I’ve come to realise crying is natural so today I will cry. I love my mum."
