News By TooFab Staff | 12/28/2010 2:26 PM PT It's been less than 24 hours since LeAnn Rimes announced that she and Eddie Cibrian are engaged, and now, a new report out is claiming that the country singer is pregnant! A source tells Hollybaby, "LeAnn thinks she's expecting. They've been trying for a while and after many pregnancy tests, she finally got the reading she was hoping for: the test was positive." Once Rimes, 28, and Cibrian, 37, tie the knot, Rimes will be a stepmom to his kids Mason, 7, and Jake, 3. Rimes' rep has not yet responded to TooFab's request for comment.
