Stars react to Khloe Kardashian giving birth

After a highly-publicized pregnancy, Khloe Kardashian gave birth to a baby girl earlier today.

From her very public struggle with fertility problems to recently leaked videos of the baby's father, Tristian Thompson, cheating on Kardashian, celebrities are taking to social media to send their love and show support to the reality star and designer.

Kardashian revealed back in December that she was pregnant to her 75 million Instagram followers, showing off her baby bump in a Calvin Klein set.

The caption read, "My greatest dream realized! We are having a baby! I had been waiting and wondering but God had a plan all along. He knew what He was doing. I simply had to trust in Him and be patient. I still at times can't believe that our love created life! Tristan, thank you for loving me the way that you do! Thank you for treating me like a Queen!..."
