Cop a gander of Christina Aguilera and Katy Perry!

The Pop superstars aligned last night at Stella McCartney‘s fashion presentation in Los Angeles, California.

Posing and pouting, the ladies turned heads – together and apart.

The sighting comes as Katy wraps up the US leg of her ‘Witness Tour’ and gears up for the March premiere of ‘American Idol.’ 

Xtina, on the other hand, is prepping a return to music scene and has cooked up new material with the likes of Anderson.Paak, Janelle Monae, and Thundercat.

Pending then, peep more pics after the jump…
