E! News confirmed the exciting news after Shayk was spotted with a growing baby bump during the 2016 Victoria's Secret Fashion Show...And yes, she still managed to rock lingerie and strut her stuff down the runway even while preggers.
Cooper has been dating the supermodel for a year and a half, and they've been showing off major PDA all across the globe since, rarely taking their hands off each other when spotted in public. We've learned that they've even been discussing marriage lately, and now it appears they're officially becoming a family by making it three.
Let's check out a timeline of their romantic road to baby so far:
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."
July 2015: E! News learned the couple had begun discussing the idea of starting a family. "They both want kids one day and that's been discussed between them," an insider told us. "They have a huge attraction to each other between their personalities and their sexual energies. You see them in a room and you immediately are in love with them as a couple."
August 2015: The pair took a romantic vacation to the Amalfi Coast in Italy, jetting off to the island of Capri where they stayed at the JK Place five-star luxury hotel. They were photographed enjoying yet another makeout session while laying on the black sand beach. They even matched in their orange bathing suit bottoms!
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! News that, although Shayk didn't spend Thanksgiving with Cooper and his family (because he was working), the pair did spend the holidays together and rang in 2016. The insider also noted that both of their families love them as a couple and are extremely happy for them.

March 2016: Cooper and Shayk made their very first red carpet appearance together as a couple, stepping out together for the L'Oreal Red Obsession Party in Paris. That same week, Cooper couldn't keep his eyes off his lady as she strutted the catwalk at Givenchy's Paris Fashion Week season debut.
April 2016: Shayk made things "officially official" (by social media standards) when she shared her first Instagram photo with Cooper. In the pic, she cuddled up to her shirtless man in a pool while wearing a cut-out swimsuit on vacation.
