Liam Payne's girlfriend Kate Cassidy broke her silence on the death of the ex-One Direction singer, saying she is at a "complete loss."

That’s obviously a huge betrayal to her, and that hurts a lot. She hasn’t stopped crying. She’s devastated,” the influencer’s friend told The Post Friday.

Local police said Payne was declared dead on the spot after falling from the third floor of the Casa Sur Hotel in Buenos Aires.
