Are Katy Perry and John Mayer ready to tie the knot?

The "Dark Horse" singer stepped out with her beau last night for dinner at Crossroads Restaurant in West Hollywood, Calif., flashing a ring on that finger as she tried to hide her face from photographers.

This is the second time the brunette beauty has been snapped wearing the massive diamond ring in the past two days!

Katy was first spotted with the sparkler after a Valentine's Day dinner with John at Sunset Towers in Los Angeles on Friday night.

While the couple has stayed mum about a possible engagement, they recently opened up to Ellen DeGeneres about their relationship.

"We have a lot of fun," Perry said. "We have music as an understanding and love between each other and we connect. It's like he understands what I do because he does the same thing. And so after a long day, if it's been tough, I don't really have to go into it. He just gets it. So it's nice with that understanding."

It definitely seems like these two are in it for the long haul!
