The 38-year-old star is spilling all after discovering her husband cheated on her with her best friend Jane Pountney in 2014, reported Female First.
"I'm going to use my experience from what happened with Kieran cheating on me with my best friend," she said.
"The truth will come out. I knew Jane had changed and I knew she fancied Kieran. Why didn't I say something instead of saying how great she looked and all of that? I wish I had clocked it before," Price added.
