April 2015: The couple was first linked together in April of 2015. They were spotted attending Broadway's Finding Neverland, just a short while after Shayk split from soccer stud Cristiano Ronaldo and Cooper broke up with longtime girlfriend, Suki Waterhouse.
May 2015: Shayk and Cooper were spotted getting cozy in both New York City and London. In NYC, they were photographed walking hand-in-hand through the city and engaging in a steamy makeout session. Just a week later, pictures surfaced of them smooching in a parking lot in London—complete with Cooper's man-bun.
That same month, a source told E! News their romance was "heating up," adding, "They have been spending lots of time together these past few weeks and have had many date nights. Their chemistry is crazy when they are together. They can't keep their hands off of each other."

September 2015: Over Labor Day weekend in 2015, the couple took their love to the New Jersey shore. They enjoyed the sandy coast where they just couldn't help but show off their beach physiques in their swimsuits. Of course, they were also spotted packing on the PDA during a dinner date, and they later enjoyed an evening with Cooper's mother in Atlantic City, who adored Shayk.
"Bradley's mother is very down to earth and just wants her son to be happy," a source told us at the time. "Irina was so pleased to spend some time with his mom. She would love a women like that to be her mother-in-law."
That month, E! News also learned that they had finally told each other "I love you." An insider revealed, "Bradley and Irina have exchanged the 'I love you's already and just really care deeply for one another."
October 2015: The pair totally revived our belief in love with some adorably playful photos in New York. Playing a sexy, little game of hide and seek, they ran and hid from each other behind a parked car as they left Cooper's Tribeca Hotel one night. He then chased her down the street, giggling and playing around, before they couldn't stand to be apart any longer, falling into each other's arms once again.
November and December 2015: A source told E!
