A popular Puerto Rican comedian and drag queen died Thursday night from a heart attack after he underwent surgery from a foot infection. Alex Soto had been recovering from the amputation of his left foot when his heart gave out, said actress Veronica Ojeda Rubio, a member of the Board of Actors Association Puerto Rico.

Fans had been collecting money to help pay for his medical treatment under a GoFundMe account titled "United for the health of Alex Soto." The funds will now be sent to his family "for use for burial or for whatever you need," Ojeda Rubio told Spanish media.

Soto was known for portraying a buffet of saucy characters and donning fanciful costumes. His routines were ripe with black humor, dancing, singing and glamor.

Soto died in Boston, Fernan Vélez, producer of the morning show The Circus, told reporters. He had previously battled diabetes.

Friends and fans took to social media to mourn him Friday. "Devastated with the departure of another great friend ... Alex Soto love you with my life and will always be in my mind, in my heart and my soul. Thanks for being a friend, a mentor and an inspiration of pride and excellence. Rest in peace next to Daddy God and put them to enjoy all up there. RIP Alex Soto, "wrote one fan on Facebook.
