John Mayer and Katy Perry are back together in a big way. It's not only good for their careers (they keep gushing about one another to the press to promote their new albums 'Paradise Valley' and 'Prism'), but also for their hearts. Turns out, Mayer is even considering taking the next step with Perry. What's that step?

Sources say Mayer has been asking Perry's pals for tips on proposing to the 'Roar' singer. Whoa!

"John has been asking Katy’s friends tons of questions, like what kind of engagement ring she would want and what the best way to propose would be," a source told Life & Style (via Starpulse).

Considering how 'Hot n' Cold' the couple have been, as well as how much of a ladies' man reputation Mayer has earned himself over the years by romancing the likes of Jessica Simpson, Jennifer Aniston, Minka Kelly, Jennifer Love Hewitt and more, the news may be a bit shocking. However, sources close to the couple say that they're both in it for the long haul.

A friend said, "They've been so serious about each other ever since they got back together (this past June)."

As for how the proposal would go down, the insider said that Mayer wants to go all out for his lady. "John wants to do something special, probably around the holidays. There are a lot of options on the table. Nothing is ruled out. It could happen on a romantic getaway or during a family dinner."

So. Flippin'. Cute! Here's hoping these two guitar-strumming 'Who You Love' singers can work it out and make it down the aisle, because as you can see here, Perry looks stunning in white.
