Gisele Bündchen and Sexy Sister Gabriela Stun at NYC Party—See the Pics!

Brazilian beauty was "so happy" her sibling was able to attend event for new BLK DNM campaign

It's no surprise that if you're a Bündchen, you're probably pretty attractive. 

Last night, Gisele Bündchen's gorgeous sister Gabriela proved that theory to be correct at a private party for the supermodel's new BLK DNM ad campaign.

Tom Brady's wife was clearly excited her sis was able to make it to NYC for the event. She Instagrammed a sweet shot of the duo, writing, "So happy by sister Gabi is in town"

Clearly, family is important to the 32-year-old Brazilian beauty. She explained to the L.A. Times that they're always on her mind—even when she's on the catwalk.

"I begin thinking about getting back to my boys once I'm nearing the exit [of the runway]," she said. "When not at work, I'm a wife, mother, daughter, sister and friend. I'm a woman trying to balance family, work and friends like so many others out there."

Well, looks like that balance is working well, because there doesn't appear to be any sibling rivalry here!
