Kanye West has been full of surprises for his three-show run at the Revel in Atlantic City. The first night showed him sporting some insane masks. He followed that up with a mid-show rant the next night. Sunday's show topped them all by announcing to the crowd that Kim Kardashian was expecting.

In the clip, West told the audience to congratulate his new “baby mom.”

Twitter is already active with plenty of congratulatory tweets. Read a few of them from the likes of Ryan Seacrest, Lamar Odom, and more.

UPDATE: Kim K confirmed she is expecting a baby with Kanye. Read her response below.

It’s true!! Kanye and I are expecting a baby. We feel so blessed and lucky and wish that in addition to both of our families, his mom and my dad could be here to celebrate this special time with us. Looking forward to great new beginnings in 2013 and to starting a family. Happy New Year!!! Xo
