There's another little Kardashian to keep up with.
Kim Kardashian announced that she and Kanye West have welcomed their fourth child ? a baby boy ? via surrogate.
"He's here and he's perfect!" Kardashian tweeted Friday.
The reality star and West are also parents to 5-year-old daughter North, 3-year-old son Saint and 1-year-old daughter Chicago.
Kardashian said the new baby strongly resembles one of her siblings.
"He's also Chicago's twin lol I'm sure he will change a lot but now he looks just like her," she wrote in a second tweet.
The announcement came a day after Kourtney Kardashian revealed during a taping of "The Ellen DeGeneres Show" that her sister's surrogate had gone into labor. Kourtney shared the news after walking onstage to surprise her mom, Kris Jenner, for a Mother's Day special.
"My mom doesn't even know this, but Kim's surrogate went into labor," Kourtney revealed. "So she's at the hospital."
Kim, 38, had planned to be there to surprise her mom, too, before the baby development.
She and her hip hop star husband turned to a surrogate for both Chicago and the new baby after a doctor advised that it wouldn't be safe for her to carry another child following complications with her first two pregnancies.
West and Kardashian have not revealed the new child's name yet.
The "Keeping Up with the Kardashians" star had previously confirmed that she and West were expecting a boy. She denied gossip earlier this week that suggested the baby was born days ago.
"Wait just saw news our baby boy came but that's not true! It's Met Monday, I'm in NYC," she tweeted on Monday. "I would be at the hospital lol."
She was accompanied by West at that swanky affair.
