While reporters were scrambling to cover the bombings at the Boston Marathon on Monday, some of Hollywood's famous faces took to social media to send emotional support to the victims of the attack.
"My thoughts and prayers are with everyone in the city of Boston and all of those affected by this terrible incident," Justin Timberlake wrote on Twitter after the two explosions rocked Beantown.
"Captain America" star Chris Evans echoed that sentiment.
"Thoughts and prayers are with everybody in boston," he tweeted. "Heartbreaking..."
Ellen DeGeneres took a similar approach and encouraged all of her followers to do the same.
"Let's all send our thoughts, our prayers and our energy to the people injured in Boston," DeGeneres tweeted. "My heart is with you."
Zoe Saldana, who spent Sunday evening at the MTV Movie Awards promoting "Star Trek Into Darkness," took a moment to think of those who lost their lives today.
"My prayers and thoughts are with the victims who lost their lives today at the Boston marathon," Saldana tweeted. "Que Dios los tenga en su gloria."
"Clerks" creator Kevin Smith called the attack "just plain f--king evil," but remembered how lucky he and his loved ones are to not be affected by the tragedy.
"Go hug your loved ones. I'll be doing the same," Smith tweeted. "Be strong, Boston."
"Argo" director Ben Affleck, who grew up in the greater Boston area with friend Matt Damon, took to Twitter to send the "resilient" city some love.
"Such a senseless and tragic day," Affleck wrote. "My family and I send our love to our beloved and resilient Boston."
Piers Morgan, the CNN personality who broadcasts "Piers Morgan Tonight" out of Hollywood, sent his prayers into the Twitterverse after seeing the first gruesome images from the bombing.
"Some horrific images being posted on Twitter from #BostonMarathon explosions," Morgan tweeted. "Those poor people - pray for them."
President Barack Obama also expressed his "deepest thoughts and prayers" while addressing the nation on Monday afternoon.
"On days like this there are no Republicans or Democrats; we are Americans united in concern for our fellow citizens," Obama stressed.
And along the same patriotic message, Steve Martin chose to quote a verse from "The Star-Spangled Banner" -- an effective reminder of America's long history of overcoming even the worst of tragedies.
'...And the rockets red glare, the bombs bursting in air, gave proof through the night, that our flag was still there,'" Martin wrote. "#Boston."
