Google seems serious about pushing its Chrome browser, and is employing the help of Lady Gaga to make it appeal to all 'Little Monsters' out there.
Lady Gaga has a massive following. She almost bought Amazon's heavy iron infrastructure to its knees. She's the first person to hit 10 million followers on Twitter. When she speaks, people (a lot of people) listen. If a 'Little Monster' (it's what Lady Gaga calls her fans) wasn't already using Chrome browser, they will be after seeing this.
Social engineering, absolutely, but it's still genius marketing.
