Katy Perry Tributes Late 'Sister' Angelica Cob-Baehler Who Died Of Cancer

Katy Perry mourned the loss of one of her closest friends, music executive Angelica Cob-Baehler, who recently died of cancer at 47. The "Swish Swish" singer took to Instagram on Tuesday (November 27) with a heartfelt ode in honor of the woman who she attributes her rise to fame.

"Six days ago, one of my biggest champions and realest friends, Angelica Cob-Baehler moved on from this place," Perry writes in her note. "She was one of the strongest women I have ever known - fighting her cancer like friggin’ Rocky, enduring chemo, immunotherapy, a tracheotomy, feeding tubes for months on end, and experimental cancer treatment trials. I watched her go through many stages for over a year, but a few things remained constant: her sarcastic/wicked sense of humor, her positive outlook, and the incredible love she had for her family."

The Witness star, who was pals with Cob-Baehler for over 10 years, described her as a resilient, "big sister" figure in her life as well as her success. "I am incredibly grateful she was a born fighter/no s**t-taker because she practically willed me into existence as a young artist when she 'stole my files' from limbo at Columbia Records and brought them to life at Capitol Records," Perry continued.

"I have procrastinated posting this because it makes it feel a little too final, but I don’t believe people ever really die - she just had to leave that body behind," the musician added of her friend, who is survived by her husband and two daughters. "As for me, I’ll never let them forget that Angelica embodied the angel in her name, was a woman of incredible integrity and character, a massive giver, and a DOPE human being."
