Kanye West Skips Own Listening Party Amid Rumors Kim Kardashian Is In Labor

UPDATE: Kim Kardashian gave birth to a girl early Saturday, multiple sources confirm. As RadarOnline reported exclusively, Kanye West missed his own listening part for his new album and the Kardashian family went to great lengths to keep secret that Kim has gone to the hospital early.

Kanye West disappointed some of his biggest fans by not showing up at a listening party for his new album, RadarOnline.com is exclusively reporting.

But those fans are giving the rapper a break because the reason for his no-show may be that his girlfriend Kim Kardashian had gone into labor and was in the hospital.

The rumor swept through the party at Milk Studios in Los Angeles Friday night.

RadarOnline.com has not been able to confirm if Kim is in the hospital but she was represented at the event where several tracks from Yeezus were played.

Her BFF Jonathan Cheban   and sister Kourtney's baby daddy Scott Disick both attended.

So did Justin Bieber  who arrived -- and left -- with his own posse.

One sign that Kim may not be in labor is that  Kourtney tweeted that she was on a "Saturday morning jungle hike." But the accompanying Instagram photo showed only foliage, and no Kourtney. A clever ruse to draw attention away from Kim in labor? Or proof that Kim is not in the hospital?
