Back to work(ing it)! Newly-single Irina Shayk paints on a wide smile as she steps out in a chic cape coat and thigh-skimming mini for Sport Illustrated event

Irina Shayk had her business head on on Monday when she hit a Sport Illustrated event with her winning smile on show.

She may have been going through a break up with one of the world's top footballers Cristiano Ronaldo but the beauty was getting back on top with what she knows best too.

Irina, 29, looked exquisite as she arrived at Herald Square in New York, smiling widely with her show-stopping shape on show in a little black mini dress and a chic cape coat layered over the top.

Irina, supported by fellow models Lily Aldridge and Hannah Davis, to unveil the latest issue of the magazine, in which Hannah is the cover star.

Russian beauty Irina stood out among the stunning trio with her full lip pout and her long hair swept over in gorgeous waves.

The model showed off her never-ending legs in a thigh-skimming mini dress, belted with a silver chain, and pulled on a pair of sultry knee-high boots.

Over the top, she wore a simple black cape that swung just below the knee to hide her svelte silhouette. 

She was animated as she happily chatted to interviewers, despite her five-year relationship having come to an end only weeks ago.  

Irina was also forced to brush off the criticism surrounding her ex, who enjoyed a wild night of partying in Madrid despite his Real Madrid team's humiliating defeat against Atletico Madrid that day.

Ronaldo, who played the full 90 minutes last Saturday, was slammed for hitting the karaoke circuit only hours after losing 4-0 to their rivals.  

It would surely be bitter sweet for Irina to see Ronaldo enjoying his birthday celebrations, this year without her, the first time in five years.

Ronaldo's birthday was also a big milestone, as he marked his 30th last Thurday but waited until preparation for the game was over.

The next day, Irina was pictured leaving her apartment looking solemn in a chic chinchilla jacket and knee-high leather boots, swiftly escaping by a waiting SUV.

On January 21, Real Madrid star Ronaldo confirmed that his long-term relationship with the Sports Illustrated model had come to an end.

The Portuguese footballer said: 'After dating for five years, my relationship with Irina Shayk has come to an end. We believed it would be best for both of us to take this step now. I wish Irina the greatest happiness.'
