Demi Lovato vs. Taylor Swift vs. Carly Rae Jepsen vs. Mollie King: Who Is the Best Cosmo Cover Girl? – Readers Poll

Demi Lovato is the most recent pop starlet to cover Cosmopolitan, making that two Cosmo covers for the 'Heart Attack' singer within the past year!

She's had some good company on the cover of the women's mag, as fellow hit makers Taylor Swift, Carly Rae Jepsen and Mollie King of the Saturdays have all graced the front page of Cosmo this year. Of course, the question is, who gets your vote for the best Cosmo cover girl?

On Demi's August 2013 cover of Cosmopolitan, the songstress is at her absolute sexiest in a low-cut, figure-hugging orange dress. We get a peek at that sexy blue bra of hers, and the 'Made in the USA' belter also showed off some cleavage in her accompanying photo spread, which you can also see below. Doesn't she look slammin'?

Meanwhile, Taylor Swift was a bit more covered up on her issue of Cosmo in the U.K., which hit stands in Jan. 2013. She wore a purple and maroon-colored dress (or is that a skirt and top combo?) with her hair blowing in the wind. The 'Red' singer-songwriter looked sultry but in a very classy way, and the photogs used this same vibe while shooting Swift's accompanying Cosmo photo spread.

Then there's the colorful Carly Rae Jepsen, who sported a super short, printed dress in shades of green, yellow, white and black on her Cosmo cover. Her signature fringe and brown locks were done wildly and her smokey eye makeup gave some added edge. We also love all of that gold jewelry. Her photo spread is just as vibrant as her cover, too!

Finally, there's Mollie King of the Saturdays, and the 'What About Us' girl group member was scorching on her U.K. Cosmo cover in March 2013. She looked old Hollywood glam with her blonde waves, bright red lips and corset dress. The stunning Sats singer also channeled her inner femme fatale in her photo spread, showing off her legs in a long black gown with a thigh-high, zipper slit up the back.
