Earlier this week, the "American Sniper" star and Russian girlfriend had given birth to their first child.

The incredible thing is, although Irina Shayk gave birth a few more weeks ago, it hasn't come out of the news until a source revealed about it. However, Bradley Cooper's newborn's sex wasn't exposed.

Apparently, after a couple of years dating, the "Silver Linings Playbook" actor and his girlfriend had secretly engaged and got their first child. It was reported that Cooper surprised Shayk with a diamond and emerald ring as he asked her to be his wife. The proposal was confidential and although this was supposed to be a good news, those who were close to the stars knew something was happening.

Just like how normal relationship goes, Cooper and Shayk's relationship had been on the rocks. According to Radar, a source revealed how the "Burnt" star had changed his behavior before his wife-to-be gave birth.

"Bradley has never looked so miserable," a source claimed. The couple had been very public about their affection and several photos even revealed their steamy PDA makeout sessions. But, as a part of their preparation to become parents, Cooper and Shayk kept their relationship very low profile.

Meanwhile, the Victoria's Secret model had welcomed dramatic changes, especially with her lifestyle. She has been taking folic acid, prenatal supplements, and timed her ovulation cycle. A source claimed that the model loves being pregnant and that she's been happy seeing her baby grow inside.

The dark-haired beauty may have covered herself well in stylish outfits but she never failed to adjust her diet and fitness routine for her pregnancy. The pregnancy was said to bring Cooper and his girlfriend closer. Now that the baby's finally out, there's no doubt that the two were happier.
