McPhee, 31, was joined at the event by her Scorpion costars Elyes Gabel and Ari Stidham, who were there to promote the second season of their hit TV series that follows a task force of super-geniuses as they try to solve all of the world’s most pressing problems. While Gabel and Stidham play two of the geniuses on Scorpion, McPhee plays the mother to one, while also helping the group interact with people with slightly lower IQs. In addition to the Scorpion stars, the CBS soiree was also attended by stars of the network’s other shows, including, CSI: Cyber‘s Patricia Arquette, NCIS stars Emily Wickersham, Pauley Perrette and Sean Murray, and The Odd Couple‘s Matthew Perry, Lindsay Sloane and Yvette Nicole Brown. The Late Late Show host James Cordon was in attendance as well. Scorpion’s first season wrapped up in April. The show, which was renewed earlier this year, will premiere its sophomore season in the fall.
