John Mayer Posts #TBT Instagram [PHOTO] of Young Katy Perry Boyfriend, “3x5” Original Lyrics

John Mayer certainly is in a nostalgic mood today. Perhaps it is a result of it being Thursday – or 'Throwback Thursday" – but the musician recently took some time to post a couple of photos from the past to his Instagram page. Particularly one of him and an old guitar, which he still plays today, as well as the original scribbling lyrics to his hit song "3x5" off the musician's album Room for Squares. Who would have known from the looks of the little guitar player in the photo that he'd one day reach the heights he has. And of course, who would have thought that he would someday date Katy Perry... and Taylor Swift... and Jessica Simpson... and Jennifer Aniston... and others, of course.

Mayer first posted the original lyrics of "3x5" alongside the caption, "#tbt 2000 '3x5' lyrics."

Check out the posting here:

Just a bit after, the guitarist delighted us all yet again – sadly not with new music – with a photo of a young Mayer circa 1998 holding a guitar.

The pic is captioned with, "#tbt 1998... I bought this guitar in 1996 and I still play it to this day. Quite a deep thing to watch something become old in real time. It's like watching the water settle in the wake of a boat. It just happens... Anyway, stay on the boat is all I'm saying."

#Deep, dude.
