The ABC Family starlets attended the bash with good friend Kat DeLuna.
Cassie, 22, dolled up as a lioness while Francia went with a cavewoman.
Just a few days before, Francia tweeted out birthday wishes to her godson, Hudson Evangelista, co-star Allen‘s son.
“Happy 1st birthday to my little angel. The little man that stole the other half of my heart. My Godson Hudson!! @ninaaabeee @ifollowallen,” she wrote.
