Pop diva Lady Gaga thrilled Google employees during a visit to the Internet giant's headquarters yesterday in which she answered questions from tech-savvy fans.

She broke from her Monster Ball tour for an interview with Google's Marissa Mayer, who asked the singer questions submitted using Twitter or through a Google Moderator service at her YouTube channel.

"The superstar wowed a crowd in a venue that was packed to the rafters with adoring Googlers (Google employees)," the Mountain View, California-based company said in a release.

"Googlers went Gaga, channeling their inner little monsters and donning everything from her signature bow-tie hair buns to Mother Monster costumes."

Gaga, whose birth name is Stefani Germanotta, is known for daring fashion statements that include once dressing in an outfit made of meat. She refers to her fans as "little monsters."

Gaga, who will turn 25 next week, said during the Google interview that she will make her directing debut in her next video, which will be titled "Judas."

Gaga was the first artist to top a billion views at the Google-owned video sharing website YouTube.

More than 54,000 videos of questions from fans were uploaded to YouTube after she put out a message last week inviting them to tell Google what they wanted to know.

A video of Mayer's more than hour-long talk with Gaga was posted late Tuesday at a Google Talks channel at YouTube.
