Even if I am constantly seeing celebrities who carry their laptops without a bag [1], I do love the trend of celebs and their BlackBerry gels! Cameron Diaz and Jessica Biel had the same orange gel [2], while Britney rocked a light blue gel [3], and now we have edgy-fabulous Rihanna showing off a pretty-in-pink gel!

Since she matched the gel to her outfit that day, I wonder if she has many more that she rotates in and out to match her ensemble. I am building up my own mini-arsenal of colorful gels, and I may have to hit up a pink one just like Rihanna's that I found on Amazon [4], for under 10 bucks!
