Lady Gaga's latest single 'The Edge of Glory' is riding high domestically while the singer is in Europe promoting 'Born This Way,' but the Mother Monster engaged in a Twitter Q&A sesh with fans. She addressed a myriad of Gaga hot topics, such as what her next single will be, her video plans, her thoughts on her next tour and upcoming TV appearances.

When a fan asked what the next single will be, following up 'Born This Way,' 'Judas' and 'The Edge of Glory,' Gaga tweeted "I don't want to ruin the surprise! It's very unexpected. Working on the Video now : )"

She also revealed that she wants 'The Edge of Glory' to soar to No. 1 on the radio charts as a tribute to the late, great Clarence Clemons, who laid down the sax solo on the song. She posted this tweet: "Next single coming in a bit. Coming back to America for some suprise TV performances. I want to make Edge of Glory #1 for Clarence." That should be a manifesto for little monsters to flood their local radio stations with requests to play the song.

Gaga also teased her upcoming tour, writing "BTWBall dates announced soon, …I know EXACTLY what I want it to look and feel like down to every detail. Time to build."

All of this teaser info got us wondering exactly what song Gaga will go with for her fourth official single for 'Born This Way.' Piecing together info from her tweets, PopCrush is going to wager a guess that 'You & I ' will be the next one. She said it's going to be a surprise and unexpected, and since her last three singles have been dance-oriented and epic, it's about time she lets the full on rock opera be her next single.
