Talk about double trouble!
But it was something that we'd seen before!
As RadarOnline.com has uncovered, the two-time Grammy Award-winner's arch nemesis, Brandi Glanville, wore an almost identical suit just a few days earlier... just in a different color.
The Real Housewives of Beverly Hills star flaunted a blue and white version of the itsy-bitsy bikini on a Los Angeles beach for what appeared to be a staged photo shoot.
Not surprisingly, sharpshooters were quick to take aim at Cibrian's second wife though.
One armchair critic wrote on Twitter: “Leann rimes isn't even trying to hide her crazy anymore.. Same bikini as Brandi on Cabo trip???"
Do you think this latest "bikini blunder" is an innocent fashion faux pas or is the pair's rivalry heating up in a teeny bikini war? Tell us in comments, below.
