Jessica Alba and Nicole Richie Emerge as Beautiful Conjoined Twins at the Baby2Baby Gala in Los Angeles

The two starlets couldn't keep their hips or florals off each other at the Hollywood event.

We're not sure why Jessica Alba and Nicole Richie are posing like a pair of conjoined twins in a vintage sideshow poster, but it does add a level of charm to their already dainty dresses.

Alba's gown is a floor-length floral Valentino last seen in this summer's Borscht Belt revival of The Sound of Music.

Richie, who judging from her expression clearly knows all this, is in Lorena Sarbu.

Let's see how smiley Nic is after she looks down and realizes that she and Alba suddenly have to share one liver...forever.
