The recent protests by some NFL players refusing to stand during the National Anthem has celebrities speaking out.
Sunday marked the 15-year anniversary of the World Trade Center attacks on Sept. 11, 2001, and the protest -- which was started by San Francisco 49ers backup quarterback Colin Kaepernick -- didn't sit well with some football fans. "Dear @NFL, Any player wants to boycott the anthem on 9/11 should be asked to remain in the locker room until kick off," Rob Lowe, 52, tweeted. "It's not their moment."

Kate Upton also took issue with several Miami Dolphins kneeling during the anthem. "This is unacceptable. You should be proud to be an American," the 24-year-old supermodel wrote. "Especially on 9/11 when we should support each other."
Upton added: "Protest all you want and use social media all you want. However, during the nearly two minutes when that song is playing, I believe everyone should put their hands on their heart and be proud of our country for we are all truly blessed."
Her fiance, MLB player Justin Verlander, also chimed in, declaring that he would not be sitting when the National Anthem is performed. "I choose to stand. Remembering all those who lost their lives 15 years ago on 9/11," he Instagrammed. "Also, the countless who've given their lives defending our freedom here at home. #NeverForget#PatriotDay."
Meanwhile, Chris Brown chose to stay seated for the National Anthem during a charity basketball game over the weekend in Los Angeles, California, and his actions were met with bit of backlash. The 27-year-old singer then Instagrammed a photo of him seated during the song, with the caption: "Stay classy."
At this year's Summer Olympics in Rio de Janeiro, Brazil, Gabby Douglas also came under fire for not putting her hand over her heart during the National Anthem. The gymnast later issued an apology, saying she "never meant any disrespect." Here's more on that story:
