The "Keeping Up with the Kardashians" star took to social media on Monday to share the first close-up photo of the couple's baby boy.
"Psalm Ye," Kardashian, 38, captioned the sweet snap, which featured the 1-month-old -- in a white onesie -- sound asleep.
Fans immediately reacted, saying that the family's newest addition does, in fact, look like Kim and Kanye's 16-month-old daughter, Chicago. When the couple welcomed Psalm via surrogate last month, the KKW Beauty mogul mentioned the resemblance between her two little ones.
On social media Monday, many echoed the mom of four's statement. One person tweeted: "omg he is Chi’s TWIN!!!!!!!"
"So cute that’s def Chi’s twin," commented another person.
"He looks exactly like Chicago," tweeted one individual.
The pair — who wed in 2014 — are also parents to North, 5, Saint, 3.
