Gwen Stefani vs. LeAnn Rimes

Rimes, of course, is certainly no stranger to the two-piece. After all, she's not only been photographed wearing them in the past, but she's even gone so far as to actually chat about her fondness for such skimpy swimwear.

So, it doesn't come as a complete shock that Rimes found herself slipping into three different suits during one single outing as she and husband Eddie Cibrian enjoyed a little sand and surf with his two kids the day before her 29th birthday.

Meanwhile, Stefani was in the same area spending the afternoon with her man, Gavin Rossdale, and the couple's sons, Kingston and Zuma.

Sure, the rocker mom may have only given us a good glimpse from the waist up, but let's face it, that's all one really needs to see to know that this 41-year-old easily gives Rimes' bod a run for its money.
