When Whitney Port isn’t busy being a total #girlboss running her label Whitney Eve, collaborating with QVC for her own line Whitney Port and starting inspiring hashtags, the reality star is busy planning her wedding. The City alum got engaged almost two years ago to her producer beau Tim Rosenman and Whitney has been keeping her fans in the loop with frequent blog updates on her wedding plans. Yesterday, however, it seemed like the uber-busy star was finally ready to make her way down the aisle.

The designer uploaded this pic onto her Instagram along with the caption: “This is exciting!! @jade_port@bkevents.” Gorgeous embellished wedding gown, check. Wedding day perfect mani, check. Engagement ring, check. Could it be? Whitney Port is finally getting married?

We-ell, not exactly. Yes, the celeb is definitely getting married (she just had her bachelorette weekend in Vegas with her girlfriends back in August, so the nuptials must be impending). But considering that Whitney tagged her sister in the photo, plus the fact that the ring is definitely not Whitney’s engagement sparkler, it can be deduced that the lady wearing the gown is in fact Whitney’s little sister Jade.

In fact, Whitney + her sisters Jade and Paige are all brides to be. Here’s a closer look at their rings. From top to bottom: Paige, Jade and Whitney. We’d know that oval diamond and pavé rose gold band anywhere!

We know Whitney’s day is coming, but in the meantime, congrats to her lil sis!
