Cristiano Ronaldo uses hair gel. A lot of it, it seems. This upsets supermodel Bar Refaeli – so much so that she took to Twitter to complain about it during the Portugal-Czech Republic match. Well, Ronaldo’s girlfriend, Irina Shayk (another supermodel), was having none of that. Cat fight! Note: no clothes came off, unfortunately. This one stayed in cyberspace.

It’s a terrifying scenario for everyone that’s ever used email. You get something NSFW in your inbox — maybe have a laugh or two over it — and then promptly get rid of any evidence that it ever existed. But instead of hitting “delete,” you hit “forward,” and soon everyone in your address book (your friends, your mom, your girlfriend) are looking at boobies or poop jokes or, heaven forbid, booby poop jokes. Welp, international soccer star Cristiano Ronaldo is currently going through this nightmare.

One night after it was revealed on Late Show with David Letterman that Irina Shayk would be the cover model for the 2011 Sports Illustrated swimsuit issue, Shayk paid the show another visit.

This year’s swimsuit issue could mark a turning point for SI (and possibly for Time Inc.) as it uses the issue to help transition from print to digital format.

Last night, Irina Shayk was revealed as the cover model of this year’s Sports Illustrated swimsuit issue on Late Show with David Letterman – and before that, she delivered a line on the show’s nightly Top Ten.

With today’s news that Russian model Irina Shayk will be the cover model for this year’s edition of the Sports Illustrated swimsuit issue, it’s only appropriate to familiarize yourself with Ms. Shayk a bit more.

Congratulations are in order to Russia’s Irina Shayk, because she is this year’s Sports Illustrated swimsuit issue cover model. Larger photo of the cover after the jump.

Apparently, the Facebook page was a fake, and no such nuptials are set.
