LeAnn Rimes and Eddie Cibrian are reportedly using a surrogate to have their first child together after trying to have a baby for more than two years.

“The heartbreak of repeated negative pregnancy tests became too much for LeAnn,” a source tells OK! Magazine. “She desperately wants to be a mother. So they started the process of picking a woman to carry their child.”

The 33-year-old has had some practice raising kids, as she is a stepmother to Eddie’s two children — Mason, 12, and Jake, 8 — from his first marriage to Brandi Glanville.

“Life is fine just as it is. We have lots of love at home,” she revealed.
