The Keeping Up With The Kardashians star's rapper boyfriend Kanye West, 35, surprised fans at an Atlantic City concert on 30 December by announcing out of the blue that he and Kim are expecting their first child together.
Kanye revealed the happy news by asking the audience to "make some noise for [his] baby mama" and pointing to Kim, 32, who was in the crowd.
Kim later confirmed the pregnancy on her own website, saying the couple are thrilled, but also saddened that her late father and Kanye's late mother aren't with them to celebrate.
"It's true!! Kanye and I are expecting a baby," she wrote. "We feel so blessed and lucky and wish that in addition to both of our families, his mum 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!!!"
The parents-to-be spent New Year's Eve together at the 1 Oak night club at the Mirage Resort and Casino in Las Vegas, where Kim was hosting the New Year's Eve celebrations.
She tweeted en route: "So happy to be surrounded with all my friends & some of my fam! Gonna be a fun night!"
