Matt Grant says Shayne Lamas is lying about her claim that he agreed she should keep the engagement ring he gave her when he proposed during The Bachelor: London Calling's finale.

"We never discussed this.  I never said it was cool to just keep it," he told People in a Wednesday report in which he insisted no such conversation ever took place.  "If she said we spoke about it, she just made it up. Sometimes she thinks she can say anything and I'll go along with it."

Grant and Lamas confirmed that they had called off their engagement last week, leading to Lamas revealing that she was still planning to -- with Grant's approval -- keep the 2.85-carat Tacori platinum-and-diamond eternity ring in a recent interview with People.

"I have it and I am going to keep it forever for the rest of my life," Lamas told People.  "It's safe and clean and in a glass box like a glass slipper."

"Of course (he doesn't)," Lamas said when asked if Grant was fine with the arrangement. "He wants to come over and look at it."

However not only does Grant say the pair never talked about the issue, he also doesn't believe either one of them should keep the ring.

"It wasn't a 'gift' so much.  It's not a television or a handbag," Grant told People. "It's a symbol of marriage that didn't happen."

Grant told People he wants to see the ring auctioned off, with the proceeds split evenly and donated to his and Lamas' favorite charities.

"Let's have something good come out of this," he told People. "Why hold onto it? What's the point?"

Grant acknowledges that The Bachelor's sponsors were that ones who paid for the $65,000 ring, however he still feels he should have some say in its fate. 

"At the end of the day, it was mine to give to her," he told People. "And thus I'm like, 'C'mon!' I'm sure Shayne will agree it's best going to charity."
