The Real Housewives of Beverly Hills star came up with the label because, according to her, the country singer ‘sings like an angel and drinks like a fish’.
And LeAnn had the perfect passive aggressive way to bite back.
The claws are coming out: As she hit the gym last Wednesday LeAnn Rimes was wearing a T-shirt which appeared to be referencing Brandi Glanville's 'angelfish' nickname for her
The top was reportedly supposed to depict an ‘angelfish’, and it provided LeAnn with an opportunity to show that she isn’t bothered by Brandi’s remarks.
‘LeAnn does everything she can to draw attention to herself and she made that T-shirt because she knew it would get people talking,’ a source told Radar Online.

Just before she left for her workout session, the 30-year-old tweeted: ‘Loving the t-shirt my friend sent me....hysterical.’

But the row that led to LeAnn being dubbed ‘angelfish’ began when Brandi accused LeAnn of having a 'severe eating disorder' and claimed her son fell ill after swallowing one of the country star's laxatives.
Meanwhile, LeAnn has confessed that she contemplated suicide during her darkest hour, in an interview with Entertainment Tonight which will air on Wednesday evening.

The star also admitted that as a result of the way in which they got together, she still worries Eddie will cheat on her.
She confessed: 'I would be ignorant to say, and everyone else would think I am a liar if I didn’t say yes, and I have at times.'
