David Bowie’s fans are turning their mourning into creativity. It's been a week since the British singer’s death on January 10, and his loyal fans — celebrity and otherwise — are remembering him in unique ways all around the globe.

On Saturday, January 16, fellow music icon Bruce Springsteen covered Bowie’s hit “Rebel Rebel” while on stage for the opening night of his The River tour in Pittsburgh.

The Boss thanked Bowie for supporting his music “back in the early days,” and noted that the late singer had even covered some of Springsteen’s music over the years.

Cara Delevingne posted a 2012 image of Kate Moss dressed as Bowie on the cover of Vogue on Saturday to pay tribute to the glam rocker.

“#missmoss #bowie,” she simply captioned the shot. Moss previously did another Vogue cover shoot as Bowie's Aladdin Sane, complete with lightning bolt.

And Fred Armisen appeared on Saturday Night Live to pay tribute to Bowie's memorable 1979 appearance on the NBC show.

"When I was in high school and living in Long Island, I stayed up to see David Bowie play on Saturday Night Live. Watching him, for me, was a life-changing experience," the SNL alum said, introducing a clip of the singer performing "The Man Who Sold the World." "David Bowie transformed whatever space he was in, whatever medium he was using, and that night for me, he transformed live television."

A clip from a 2013 episode of The Simpsons, featuring Bowie’s song “All the Young Dudes” and a cartoon version of Harry Potter actor Alan Rickman (who died on January 14, four days after Bowie), has also resurfaced online.

Some other tributes were less high-profile, though just as poignant. In Austin, a street sign was changed to David Bowie Street; in South London, a graffiti mural of Bowie as Aladdin Sane was littered with flowers and letters; on the Hollywood Walk of Fame, fans left memorabilia, flowers and candles around his Hollywood star.

In Belgium, astronomers paid tribute to the rock legend by dedicating a constellation to the self-proclaimed Starman. The constellation is made up of seven stars that, when connected, form the iconic lightning bolt associated with Bowie.

And late last week, a petition calling to rename Mars after the "Life on Mars" singer began to circulate online.

“[Bowie] has immortalized himself like no other. He has delivered to us accolades and art like no other,” the petition reads. “The biggest accolade we can give back to this great man and in his memory — Rename planet Mars after him. If you agree then sign this petition and share.”
