Bradley Cooper And Model Fiancee Irina Shayk Welcomed Their First Child

Bradley Cooper and Russian-born model girlfriend Irina Shayk had their first child, a source has told PEOPLE.

Incredibly, the birth took place two weeks ago and the secretive duo's happy news hadn't leaked out until now, the publication reported on Sunday.

So far, the sex of the baby hasn't been divulged.

Cooper, 42 and Shayk, 31, welcomed their child after about two years of dating.

According to RadarOnline.com sources, Cooper and Shayk secretly got engaged, but before the birth, the couple's relationship had hit a low point.

"Bradley has never looked so miserable," a source told RadarOnline.com about witnessing the way the Silver Linings Playbook star acted around his model fiancée.

Shayk covered up her baby bump at the Victoria's Secret Fashion Show, and as RadarOnline.com reported, adjusted her diet and fitness routine for her pregnancy.

Now, the wait is over and they are reportedly proud parents!

Reps for Shayk and Cooper did not respond to requests for comment
