LeAnn Rimes admits that after cheating on her ex-husband with current husband Eddie Cibrian, and years of feuding with his ex-wife Brandi Glanville, she wished she "handled it differently."
"I don't like the word regret...I wish I handled it differently because I wish I could have been better for me, for Brandi, for Dean, for Eddie, for everyone else," Rimes told E! correspondent Giuliana Rancic in the upcoming "E! Special: LeAnn Rimes."

"All I wish is that everybody we hurt, that I hurt, can be happy," Rimes said while crying.
Rimes also cried while trying to explain why she and Cibrian, 39, started an affair while they were both married. They met in 2009 while filming the television movie "Northern Lights."
"I don't think anything can separate anything that's super-connected," said Rimes.
The country singer then tried to justify their cheating by suggesting that their first marriages were "broken" at the time the affair began.
"You might have had so many wonderful things with each other's spouses in your relationship, but something along the way broke that," she added. "You can't break what's broken already."
Rimes and Cibrian's relationship began while the country singer was married to Dean Sheremet and the "Playboy" actor was wed to Brandi Glanville. They both divorced their spouses and wed in April, 2011.
"No one will ever understand how much thought and hurt were put into our decision to end (our) respective marriages," Rimes added.
Rimes and Glanville, 40, have been in an ongoing Twitter war, particularly over the 30-year-old's co-parenting skills.
The "Real Housewives of Beverly Hills" star expressed her frustration on Twitter recently after Rimes referred to her sons, Jake and Mason Cibrian, as "her boys."
Glanville claimed that Rimes has an "eating disorder" and Cibrian released a statement that his ex-wife has "severe mental issues."
"E! Special: LeAnn Rimes" will air on Sunday, Dec. 9 at 8pm EST on E!
