Do You Know Anybody on This Picture? Hint: Cooper

Anderson Cooper has been spotted partying in Rio de Janeiro with his boyfriend Ben Maisani, Bravo host Andy Cohen and a slew of new friends at events celebrating the city's annual Carnival.

Twitter was ablaze on Saturday night with news that the CNN anchor was watching the Champions Parade at the Sambadrom, which came four days after the main part of the Carnival.

'I arrived in Rio yesterday,' he told Brazilian reporters as he attended the event as a guest of beer company Devassa. 'I watched the Carnival once in Manaus. This event is known worldwide.'

But when asked if he would walk in the parade, known for its scantily-clad samba dancers and huge, colourful floats, he said no because 'my business is watching'.
