A source close to the 35-year-old reality star tells ET that both 9-month old Saint and 3-year-old North were in NYC this weekend with their dad, Kanye West, a family friend and their nanny. More specifically, North was at a performance of the musical Matilda. A rep for the Broadway production based on the classic children's book by Roald Dahl confirms to ET that North -- joined by two other children, a nanny and security guard -- saw the matinee showing of Matilda on Sunday afternoon.
After the show, the group went backstage to meet cast members of the production, though Saint was not present, the rep adds.
Kim returned to NYC on Monday
and was quickly reunited with Kanye, who abruptly stopped his show at the Meadows Festival in Queens, New York, mid-song on Sunday, citing a "family emergency."
NYPD vehicles were outside the couple's apartment in the city, along with several barricades, a source tells ET.
Kim's mom, Kris Jenner, as well as Kris' boyfriend, Corey Gamble, were later spotted at the residence. The mother of two's close pals, La La Anthony and Jonathan Cheban, also paid Kim a visit shortly after her return to the U.S.
Her sisters, Kourtney Kardashian and Kendall Jenner, were in France for Paris Fashion Week at the time of the incident, but it's not known if they too have returned to the U.S.
Our source spotted one of E!'s cameras at Kim and Kanye's residence on Monday, which could mean Kim is continuing to film Keeping Up With the Kardashians
. But in a statement on Monday to ET, an E! spokesperson said that the hit show was not filming at the time of Kim's robbery.
"All of us at E! are incredibly thankful that Kim Kardashian West is safe, and we send her and her family our love and support," the statement reads. "Keeping Up With the Kardashians was not filming at the time of the robbery. Our focus right now is entirely on Kim's well-being."
Reports claim that $10 million worth of jewelry
was stolen from Kim on Sunday, when armed, masked men dressed as police officers entered the luxury apartment she was staying at in Paris during Paris Fashion Week. Stolen items reportedly include one ring worth $4 million, and a jewelry box with another $6 million worth of items.
A number of celebrities have shown their support for Kim
after the scary incident, including actress Salma Hayek, who pointed out that, thankfully, North was not present during the robbery.
"I know it's terrible, but thank God she's OK," Hayek -- who's married to French businessman Francois Henri-Pinault -- told the Associated Press about Kim when asked about the incident. "And thank God her little girl was not here so… I know it's horrific, but at least there were some good points in that the little girl was not here and that she's fine."
