Celebrity sports fans from around the world are paying homage to NBA legend Kobe Bryant after he died in a helicopter crash in California on Sunday.
Bryant was one of nine people on a private helicopter that went down in Calabasas, California, on Sunday, killing everyone on board. He was 41 years old.
Bryant's 13-year-old daughter, Gianna, was also killed in the crash, according to the NBA.
"Please no. Please god no. It can't be true," Cleveland Cavaliers player Kevin Love added.
NBA legend Michael Jordan released a statement saying, "I am in shock over the tragic news of Kobe's and Gianna's passing. Words can't describe the pain I'm feeling. I loved Kobe -- he was like a little brother to me. We used to talk often, and I will miss those conversations very much. He was a fierce competitor, one of the greats of the game and a creative force."
"Kobe was also an amazing dad who loved his family deeply -- and took great pride in his daughter's love for the game of basketball," Jordan continued. "Yvette joins me in sending my deepest condolences to Vanessa, the Lakers organization and basketball fans around the world."
"I’m stunned. Words can’t even come close to describing it. Just an incredibly sad and tragic day," Pippen, an NBA Hall of Famer, tweeted.
"It's a shocker to everyone, unbelievably said, and one of the more tragic days that -- well, for me the reality is just setting in," golfer Tiger Woods said in an interview after finishing his final round at the Farmers Insurance Open. He said he was told of Bryant's death just after leaving the 18th green and was unaware why people were shouting "Do it for Mamba" during his round.
Hall of Famer and 11-time NBA champion Bill Russell tweeted an image of he and Bryant along with a caption that said he was praying for his wife and children.
"Jeannine & I are absolutely shocked to hear of the loss of one of my favorite people & one of the best basketball minds in the history of the game! Our hearts & prayers to Vanessa & his girls. @kobebryant," Russell said. "You were my biggest fan, but I was yours #RIPMAMBA "
Twitter temporarily wasn't working at around 3 p.m. ET as news of the player's death flooded the platform. The term "Kobe" quickly became the No. 1 trending topic on Twitter, followed by "Mamba" and "BlackMamba."
"Can’t be true. Just can’t be. Truly truly horrific. Rest In Peace Kobe," NFL player JJ Watt tweeted. Similarly, Wade said, "Nooooooooooo God please No!" In another post, Wade added: "RIP Kobe + GiGi ❤️💔 I know you said keep going but today we can’t. We love you and we’re gonna miss you brother."
The world of hip-hop also mourned the NBA champion's death, with Drake posting a mural of Bryant on Instagram and R&B singer John Legend reminding fans to hold their loved ones close.
"I'm so sad and stunned right now. In Staples Arena, where Kobe created so many memories for all of us, preparing to pay tribute to another brilliant man we lost too soon, Nipsey Hussle," Legend, who was preparing for the Grammy Awards, tweeted. "Life can be so brutal and senseless sometimes. Hold on to your loved ones. We miss you, Kobe."
The mayor of Los Angeles, where Bryant spent his entire 20-year career with the Lakers, also mourned the player's death.
"This is a moment that leaves us struggling to find words that express the magnitude of shock and sorrow we are all feeling right now, and I am keeping Kobe’s entire family in my prayers at this time of unimaginable grief," Mayor Eric Garcetti said in a statement.
Here's a look at how other celebrity fans are mourning the basketball star's death:

Former NBA player Jalen Rose
On Jan. 22, 2006, Rose, who was playing for the Toronto Raptors, faced off against Bryant with Lakers when Bryant scored a historic 81 points. It was the best game of his career. Rose is now an ESPN sports analyst.
“We couldn’t’ stop him clearly,” Rose, who tried to block Bryant during that game, told ABC News. “We joked after the game, at least we kept him under a hundred points -- how about that?”
“I’ll miss most somebody that continued to beat to their own drum, was never phony, but yet always found ways to not only stay true to himself but a lot of times early in his career… He was somebody that was in the gym working. He wasn’t partying, he wasn’t out trying to drink, he wasn’t doing all of that,” he said.
“He was really trying to be better than Michael Jordan. And I’ll remember somebody that took that challenge head on and got as close as anybody will ever do.”
