Celebrities around the world sent tweets out in the aftermath of Hurricane Sandy, which has killed at least 46 Americans.

Jennifer Lopez wrote, “To all my #JLoVERS all over the world and back home... I love you.. Sleep tight... #BeSAFE'

Britney Spears tweeted: "Sending Love to the East Coast! Hope u all are staying safe & dry - keeping u in my prayers."

"I have faith that the search and rescue teams will be able to help those in need right now so that the death toll doesn’t climb any higher, and send a big thanks to the amazing relief teams!! Stay strong east coasters!" Kim Kardashian wrote.

Meanwhile, Lady Gaga, who is currently in Puerto Rico, wrote a longer post on her official website titled, ‘Hurricane Blues.’

“I’m not sure where to put these feelings. Im[sic] so sad. I feel like my entire childhood is underwater. The boardwalk in Atlantic city, my old Apts in Brooklyn and LES. All the bars and friends.

I’m just so sad. I know it will be ok. Im [sic] not sure why I feel this way. maybe homesickness, or maybe its[sic] easier to be a gypsy if you know your soul grows from somewhere great, and that great place protected me my whole life, now parts are destroyed. just [sic] very sad and pensive today. Thinking of everyone today.” 

Hurricane Sandy has left the East Coast devastated. Millions of people are not able to get to work, and millions of others are without power. 

"We will get through the days ahead by doing what we always do in tough times — by standing together, shoulder to shoulder, ready to help a neighbor, comfort a stranger and get the city we love back on its feet," New York Mayor Michael Bloomberg said in a news conference.
