Stephanie Romanov (Nikki Ellston)
Back during season two, Nikki came in as the ex of Elliot who dates Dennis. Of course, if you remember her strange antics involving a bird cage, you know her relationship with David did not last. Like some of the other women on our list, Romanov rose to popularity with her modeling. However, she then chose to pursue acting and has appeared in things like Hotel Alexandria, Seven Days, The Closer and in the Buffy the Vampire Slayer spin-off, Angel. Actually, she even starred with Robin Williams in The Final Cut.
Amy Sedaris (Betsy Frayne)
When Jack Gallo searches for a new security team member, he hired Betsy played by Amy Sedaris. Remember how David Finch knew Betsy from college and claimed she stole his personality? Ah, only David. Anyway, since then, Amy has had roles in Raising Hope, Horace and Pete and Broad City. She also starred in The Heart She Holler, Alpha House and as Princess Carolyn in BoJack Horseman.
