In yet another Bachelor engagement disaster, Matt Grant and Shayne Lamas are calling it quits, and with good reason!

“I’m used to the Hollywood BS,” Shayne told Us Weekly. “But it really got into Matt’s head.”

While that tends to happen, Matt’s buddies said it’s just the opposite. “After he moved to L.A. and saw her constantly partying and clubbing, he realized that she wasn’t behaving like a woman who was ready to be in a serious relationship,” the source said.

I could’ve called this one!

A diamond is supposed to be forever, but not for the latest Bachelor Matt Grant. Amid rumors of infidelity, Season 11 Bachelor Matt Grant and ex-fiance Shayne Lamas have called it quits, but not so fast.

Yesterday, Lamas told People.com, “I have it and I am going to keep it forever for the rest of my life … It’s safe and clean and in a glass box like a glass slipper.”

Obviously, she is talking about the 2.85 carat diamond that Grant presented to her during the finale. However, Lamas’ Cinderella story isn’t ending too nicely, if Grant has anything to say about it!

“We never discussed this,” he tells People.com. “I never said it was cool to just keep it. 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.”

Matt adds, “It’s not a television or a handbag. It’s a symbol of a marriage that didn’t happen.”

Wow! It looks like it is going to be a war of words between the Bachelor and his wilted rose.

She drank too much and inappropriately slipped new Bachelor bloke Matt Grant her lace thong while he was chatting with another cast member. Yikes!
