Public Readings - 'The moment you find out your ex is engaged to the girl he cheated on you with!' Chad Kroeger's ex-girlfriend claims rocker was seeing Avril Lavigne behind her back.

His former flame has accused the Nickelback rocker of cheating on her with the Complicated singer.
Kristen, 27, has also taken to Twitter in a bid to articulate her shock, saying: 'the moment u find out ur ex of four months engaged the girl he was cheating on you with! #classic.'
However, she then wrote: 'Thx for the sweet comments! Sometimes 140 characters is just not enough for what I would like to say! #whatgoesaroundcomesaround. Learned a lesson. Moved on.'

According to RadarOnline, 27-year-old Kristen (the same age as Avril) had been dating Chad for several years following his breakup from long-time Canadian girlfriend Marianne Goriuk in 2002.
A source said: 'Chad and Kristen were happily dating until they made a mutual split in May.

In July 2006, at the tender age of 21, she wed Sum 41 rocker Deryck Whibley in a fairytale wedding.
However, it was not to be and she filed for divorce a little more than three years later.
She then moved on to Kim Kardashian's stepbrother Brody - even getting a tattoo of his name beneath her right breast - before they split in January after nearly two years together.
Meanwhile, Chad spent six years with Marianne Goriuk prior to Kristen.
