'90210' scoop: Keke Palmer joins the show as Jordan's sister
Palmer will play Elizabeth, the younger sister of Jordan (played by "Hellcats" star Robbie Jones). Jordan, a suave publisher, is introduced as a new love interest for Naomi. Naomi first meets Elizabeth at a masked ball, and, naturally, Elizabeth keeps her identity a secret. Let's just say it's not the most pleasant surprise for Naomi.
Elizabeth's storyline will carry through several episodes.
"90210" returns to The CW on January 21 with no shortage of drama. Check out the trailer for the second half of Season 5 below.
