Mrs. West and her expectant sister hit up Serafina restaurant in NYC around 4:30 p.m. on Monday, where they created a major distraction for those trying to watch the World Cup game.
Namely, Kim's cleavage became the main attraction (and for good reason).
When the sisters arrived, the crowd at the Meatpacking eatery was already riled up thanks to a World Cup viewing party, but things got really crazy once the E! stars set foot in the door.
"Kourtney managed to slip in without too many people noticing," an eyewitness tells E! News. "But when Kim walked in behind her, forget it. She was wearing a top with a super-plunging neckline and no bra. People's mouths dropped. Everyone immediately got out their cell phones and started taking pictures. It was as if the World Cup wasn't even on anymore, THEY became the main attraction."
Leave it to the Kardashian clan to steal the spotlight!
Since the downstairs was so packed, Kim and Kourtney requested a quieter table upstairs. The two then enjoyed a carb-filled feast, which included two salads, a truffle pizza, a focaccia dish, a pasta dish and a plate of chicken paillard (yum!). Both girls stuck to iced tea as they dined together and enjoyed some quality sister time.
"They both shared all the dishes family-style," the eyewitness adds. "Neither were on their phones a lot, they were both in deep conversation with each other the whole time."
North West's mama has been putting her world-famous curves (and post-wedding figure!) on full-display as of late.
Over the weekend, the 33-year-old beauty cheered on her hubby Kanye West while he performed at the Bonnaroo Music & Arts Festival in Manchester, Tenn.
Her outfit of choice for the occasion? A completely sheer white top that showed off her killer cleavage which she paired with a nude bra, white denim jeans and an olive green cargo jacket.
Hey, if you've got it, flaunt it, right?
