LeAnn Rimes‘ romance with Eddie Cibrian hits major roadblock – his mom!

The CSI: Miami hunk’s mother Hortensia disapproves of his affair with the Grammy-winning singer, and refuses to meet or even speak to LeAnn, pals say.

"LeAnn is completely stressed," an insider told The ENQUIRER.

"She was hoping her new life with Eddie would have a happily-ever-after ending. But that’s not happening because Eddie’s mom is horrified that he ran off with her and ditched his wife Brandi. She sees LeAnn as a home wrecker!"

Adding to LeAnn’s insecurity, Eddie still hasn’t introduced her to his sons – Mason, 6, and 2-year-old Jake.

"LeAnn desperately wants to meet the boys, but so far Eddie hasn’t let her," the source revealed.

"When they hang out, it’s usually just the two of them. Eddie’s friends and family still haven’t adjusted to the idea of LeAnn on his arm.

"Hortensia is hoping it blows over soon and he goes back to Brandi," added the source.
