Lady Gaga, Rihanna Celebrate 2010 Achievements, Stars Bemoan Blizzard In Today's Tweet Dreams

With Christmas firmly in their rearview mirrors, celebs are now focused on New Year's Eve, and thus, reflecting on the year that was 2010. Plenty of stars can boast that this was one of their biggest years, including Rihanna, who celebrated a recent milestone on Twitter with her followers today, "Yo seriously, shout out to the #LOUDEST fans in the world for takin this 2 million worlwide! Big up ya self#out2all." But, Rihanna wasn't the only one blowing up the charts this year, just look at Lady Gaga! The game-changing Grammy-nominee (pictured) wrote from her page, "THE FAME MONSTER was named the best-selling album of 2010! I'm so excited for the future, believe + work hard, you will achieve your dreams."

While famous faces in Hollywood stayed warm (Rihanna spent her holiday in Barbados!) and celebrated the end of the year, those on the other side of the country were stuck inside due to the massive blizzard (better known as Snowpocalypse) which hit over the holiday weekend. As singer/actress Naturi Naughton put it, " Omg!This snow outside is ridiculous! East Coast got smacked with this blizzard!" Still, rapper 50 Cent thought of a way to make the best of a chilly situation, as he posted, "I'm going out to shovel snow and see if I can make me a few extra dollars today. I'm charging more if they want to take pictures."
