Lady Gaga wore a blue bandeau bikini top and printed sarong to wave to fans from her hotel balcony in Rio de Janeiro yesterday. Even though she’s been busy with performances for her Brazilian fans, Lady Gaga has kept on top of all the big news coming out of the US, including yesterday’s presidential election, which saw Barack Obama re-elected for a second term. She excitedly tweeted, “I JUST GOT OFF STAGE IN COLUMBIA!! CONGRATULATIONS MR. PRESIDENT @BarackObama We are so proud to be American tonight! YES!!! YES! YES!!” and had been encouraging her Little Monsters — more than 31 million on Twitter — to vote. The musician has also made a generous donation to Superstorm Sandy relief by giving $1 million to the Red Cross.
