John Mayer rips out a million hearts with his tender cover of Beyonce's "XO." After debuting the rendition on his Australia Tour, the singer-songwriter headed into the studio to deliver an official version--flipping the R&B; diva track into a soft, heartfelt ballad.

On the three-minute track, Mayer utilizes only a guitar, piano and harmonica to pin to the lyrics. He's a marksman with music and will be releasing this performance to iTunes Tuesday (May 27). Talk about a real treat!

Even though he's no longer with Katy Perry, Mayer digs into the love-strewn song to deliver a truly great song. Is this his not-so subtle way to beg for her back? We can only dream.
