Katy Perry and John Mayer were seen, once more, getting cozy during a Grateful Dead show.

John Mayer guest-hosted 'The Late Late Show' last night (Feb. 4), and of course, he couldn't resist gushing about Katy Perry's epic Super Bowl performance.

Juan Pablo Galavis has drawn so much negative attention that even John Mayer is weighing in with his two cents! (Who knew he was a secret 'Bachelor' fan?) Mayer took to Instagram yesterday, March 12, to share with fans his complete facial analysis of Galavis, who has been labeled "Worst Bachelor Ever" by fans and celebrities alike.

On, off, on, on, off. Up, down, up, down. Katy Perry and John Mayer's romance sure is a roller coaster. Months after reports that an engagement was inevitable and weeks after Perry was seen wearing a rock on that finger, the musical duo is said to have split… again.

A few months ago, an insider said that a Katy Perry and John Mayer engagement was inevitable and that they were on that path. Did they finally become betrothed?

Katy Perry has revealed why she and boyfriend John Mayer broke up last spring and the true reason she split with husband Russell Brand in her January 2014 Marie Claire cover. She looks pretty bangin', BTW!

Even though Katy Perry's first marriage ended in divorce after only 14 months, the singer's relationship with reformed Lothario John Mayer is going so well (despite that hiccup this past spring), that sources say it's pretty certain that they will get engaged.

If the matching patriotic shirts from Fourth of July didn't convince you that John Mayer and Katy Perry were an item and "on" again, perhaps this video of Mayer, revealing how and why he fell in love with "my Katy" while performing a 'A Face to Call Home,' will...

Katy Perry stepped out on Valentine's Day with a gift from her boyfriend John Mayer: a heart-shaped ruby ring that she wore on her left ring finger to make the paparazzi explode. TROLOLOLOLOLO. Now rumors are flying that the couple plans to wed, despite their reps neither confirming or denying an engagement.

Are Katy Perry and her beau John Mayer moving at a breakneck pace? Yeah, they are, if you believe the rumors that suggest Perry is looking to settling down and start hearing the pitter patter of little feet -- and that she has been bitten by the need to nest.

Ho ho ho! John Mayer is so much more than a cad with a big mouth when it comes to relationships. The singer-songwriter and guitarist is also a great role player. His GF Katy Perry tweeted a picture of him in a Santa Claus costume -- giving off a sly grin in place of the furry white beard -- on Christmas.

Katy Perry and John Mayer really are dating, you guys! The couple were spotted out with Mayer's father, Richard, in N.Y.C. Wednesday night (Dec. 12), as they  headed to dinner and the newest show on Broadway, 'A Christmas Story.' Yes, there's a broadway version of one of our favorite holiday movies, but we digress.
