Avril Lavigne and Nickelback's Chad Kroeger had only been dating a month before he proposed last August.

According to Life & Style, they plan to get married on June 15 in her native Belleville, Ontario. Avril, 28, picked out his and hers Neil Lane wedding bands — which you can see here — and a source described Avril's as a petite pave diamond eternity band with Chad, 38, getting a matching wide modern platinum band.

An eyewitness told L&S Avril came to the Neil Lane Beverly Hills store alone. "She worked with the staff and seemed very excited about her wedding!” As all brides should be!

Avril was previously married to Sum 41's Deryck Whibley. "There's going to be a theme," Avril told Chelsea Handler of this new wedding. "I want to have a lot of fun with it and go kinda nuts this time. ... Like crazy attire and colors."

Should be interesting. Good luck to the happy couple!
