The 'Real Housewives of Beverly Hills' star - whose ex-husband Eddie Cibrian left her for the singer-and-actress in 2009 - is backing her former love rival after she checked into rehab to be treated for anxiety and stress.
Brandi - who has sons Mason, nine, and five-year-old Jake with Eddie - told Usmagazine.com: ''I totally support LeAnn's decision to enter rehab - my top priority is my children, and at the end of the day we are a family.
''LeAnn is their stepmom, and they love her. I am wishing her all the best and I Hope she will find what she is looking for while in rehab.''
LeAnn checked into an in-patient facility on Wednesday (29.08.12), a day after her 30th birthday, and Hopes the stint will help her better able to deal with her problems on her return home.
She said: ''This is just a time for me to emotionally check out for a second and take care of myself and come back in 30 days as the best 30-year-old woman I can be.
''All the things in my life will be there when I get out, but you know what? I'm hoping they're not going to affect me as much. I'll have the tools to know how to deal with them.''
