Pete may soon be a papa, but he's not giving up any of his rock 'n' roll antics just yet!

It's no surprise that we are massive Pete Wentz fans, but we love him even more after watching Fallout Boy's performance at BBC Switch Live.

At the end of a wicked set, Pete made the audience's dreams come true and dived into the crowd head first.  After getting back on stage, he throws his mic in the air and leaves in true rockstar stylee.

However, we're sure that Pete will curb his wayward behaviour once lil' Pete Jnr. is born.

Check out why we love him so much...
