Christina Milian is happily expecting her second child with French artist Matt Pokora, but many moons ago she used to date Nick Cannon.
Back in 2005 Christina and Nick spent three years together. The duo was even living together thinking it would last forever, but with a turn of events they suddenly broke up.
Most recently, Christina visited E! News and let them know why that relationship ended.
Milian told E! News that she suspected towards the end of their relationship that he was cheating on her then confirmed it by hacking into his phone and looking at his messages.
Check out the entire story in her own words below. Have you ever gone through your partner's cell phone? Let us know in the comments. We promise we won't tell! :)
