LeAnn Rimes became deeply angry when her husband’s ex-wife, Brandi Glanville, failed to tell her about a problem that landed Eddie Cibrian’s 10-year-old Mason in the hospital.

According to the NY Daily News, Rimes tweeted on Sunday, "Got a text from a friend at 4:30am asking if mason was ok. THANK GOD! Mason just called Eddie himself!!"

Everything turned out to be fine with Mason, but Rimes was deeply upset about not being notified. Mason is Eddie Cibrian’s son with Glanville. Cibrian is best known for his role as Cole Deschanel on Sunset Beach. Eddie Cibrian and LeAnn Rimes have a new reality show. Some of it takes place in Hawaii. Glanville is featured on the show, The Real Housewives of Beverly Hills, that has been on Bravo since 2010.

LeAnn Rimes is a country music star who is most recently known for her song, Can’t Fight the Moonlight, according to the Mirror. Rimes’ albums include Blue. She has received many accolades for her work, including two Grammys, three ACMs, and one American music award.
