When Nickelback frontman Chad Kroeger popped the question to Avril Lavigne in the spring 2013 he presented her with a very impressive 14-carat pear-shaped diamond ring . Now, more than a year later and on the couple’s first wedding anniversary the rocker has gifted his wife with an even more amazing sparkler. A massive 17-carat diamond ring, to be exact. The “Smile” singer shared a snapshot of the blinding bling on Twitter today and you may want to don your shades before you sneak a peek.
