[FLASHBACK: Kanye Announces His ‘Baby Mama’ Kim Kardashian… (VIDEO)]

According to E!, Kardashian gave birth to a daughter at Cedars-Sinai Medical Center in West Hollywood, yesterday (June 15, 2013) just in time for Father’s Day.

And despite earlier reports that he’d rather be anywhere but the hospital during deliver, Kanye was right by her side for the delivery.

? 18 years, 18 years! She got one of your kids, got you for 18 years. ?

Details below…

So far, Kim has uncharacteristically been quiet about the news and? hasn’t Tweeted about the birth and her publicist Jill Fritzo is not responding to repeated requests for comment.

She and West have not revealed the name, but according to E!, Kardashian told friends it will begin with a K.

Several celebs have already started congratulating the couple via social networks like twitter:

Russell Simmons: “There is no greater gift in life than a child’s laughter! congrats to Kim And Kanye…”

Nas: “Congrats to Kanye 4 the birth of his daughter today too! To my bros w/ daughters!!”

Bethenny Frankel: “All kidding aside, congrats @kimkardashian on your baby girl. It’s the most beautiful, best thing that could happen to you. Girls rule.”

Us Weekly cites an unnamed hospital source as saying the reality star delivered “five weeks early. Kim got sick last night and had the baby early.”

The source added, “They’re all doing great and amazing!”

TMZ reports that Kardashian had a natural birth after beginning contractions on Friday and going into full labor on Saturday and that Kanye was there for the entire process.

Our sources say BF Kanye West was there for the entire thing — in the delivery room by Kim’s side. We’re told Kanye cancelled his appearance at his own record release party last night when Kim told him she was feeling “a little off.”

It is the first child for both the superstar rapper and his ‘baby mama’/reality tv star, Kardashain, who felt ‘some kinda way’ about her expanding waistline.

As you know, just days ago one of Kanye’s jumpoffs sold her story to the tabloids stating she and West were involved AFTER Kim has gotten pregnant, while Kanye’s reps deny the story.

Whether the ‘cheating’ story is true or false remains a mystery, but the real story begins now that Kim has given birth.

Will Kim forever remain a ‘baby mama’ or will Yeezus eventually make his ‘baby mama’ a wife?

Stay tuned…

Congrats to the happy couple on their new arrival!
