Groups Girls' Generation and Super Junior-M were chosen to take part in Google's April Fool's Day event and gained much attention.

Every year, Google holds unique events for April Fool's Day, and this year, Gmail reached their 10th anniversary and they decided to use 'selfless' of the top trending celebrities to use as the background for gmail.

A different top trending celebrities photo was used every hour on the background and gained much attention.

For Korea's top trending celebrities, Girls' Generation and Super Junior-M were chosen and their selfies were used on both April 1 and 2.

Other top stars that were seen for this event were Katy Perry, Shakira and others.

On the other hand, Girls' Generation and Super Junior-M are both busy with their album promotions and tours.
