Kendall Jenner flashes underboob as she celebrates friend's birthday with Bella Hadid and Hailey Baldwin

Kendall Jenner, Bella Hadid and Hailey Baldwin brought out some of their best looks to celebrate their close friend's birthday!

The star-studded group stepped out at New York City's Cipriani on Wednesday night for friend Renell Medrano's birthday dinner, where they serenaded her in by a raucous rendition of "Happy Birthday" and soaked up each other's awesomeness over pasta and wine. But it was their outfits that made headlines.

Jenner, in particular, truly went for it with her ensemble. The "Keeping Up With the Kardashians" star donned a teeny white crop top that flashed a bit of underboob, a green mini skirt and red heels.

Hadid went for a less flashy ensemble, going all-black in a long-sleeved mini dress and knee-high boots and accessorizing with plentiful gold jewelry and a '90s-style mini purse. Baldwin got the most decked-out of the trio, rocking a strapless mini dress with a plunging neckline, sheer booties and gold hoop earrings.

The tight-knit group has been spending a lot of time together in New York City this summer, rocking a handful of head-turning fashions.
