Katy Perry Fuels Engagement Rumors With A Giant Diamond Ring On Her Left Hand

Ok, after seeing these photos, we HAVE to wonder whether John Mayer got down on one knee and proposed to Katy Perry over the Valentine's Day weekend!

Katy and her steady beau dined at Crossroads Restaurant in Los Angeles on Sunday, and yet again she flaunted a giant sparkler on her left ring finger! On Friday night we caught the two leaving the Sunset Tower hotel and heading to Bootsy Bellows, and she was wearing the bauble then too, but we didn't get a good peek at it.

But here's the thing -- Katy loves wearing rings, and don't you think if the duo got engaged, someone would have leaked the news to the press? This is also the second Valentine’s Day in a row where Perry has worn a ring on her left hand -- last year she showed off a heart-shaped ruby ring.

Do you think John and Katy are engaged?
