Men everywhere please try to keep it together: The 2011 Sports Illustrated Swimsuit Issue has arrived.

Following in Brooklyn Decker's formidable footsteps is this year's cover star Irina Shayk, the Russian A|X Armani Exchange model best known for dating footballer Cristiano Ronaldo.

The first Russian beauty to grace the magazine's Swimsuit Issue cover, Shayk busts out of her pink and yellow Sauvage by Elizabeth Southwood string bikini accessorized with an Ettika bracelet, long beachy waves, and serious cleavage, naturally.

Photographer Bjorn Iooss snapped the steamy image on an idyllic Maui beach.

Decker (who parlayed her cover success into a starring role in Just Go With It), Victoria's Secret Angel Izabel Goulart, Anne V., Hilary Rhoda, and Damaris Lewis are among the other notable bathing beauties slipping on their bikinis for the issue.

And techies take note: Sports Illustrated is bringing the issue to life with more than 1,300 photos and 100 videos; apps for the iPad, Galaxy, iPhone and Android; and special features including a 3-D photo shoot—we thought the images were sufficiently popping off the page already—for Sony PlayStation and a look at how rookie models were covered in bodypaint for a particularly revealing shot.

The issue hits newsstands February 15 ... so maybe now's the time to pull a sickie?
