George Takei, Nicole Richie signed for NBC's "New Normal"

A “Star Trek” veteran and, um, a socialite daughter of a famous singer are about to get “normal.”

George Takei and Nicole Richie (I leave it to the reader to figure out who is who from the previous sentence) will appear on “the New Normal.” Executive producer Ryan Murphy, who co-created “Glee” and “American Horror Story,” announced the move today on Twitter.

"Proud to announce Nicole Richie and the legendary George Takei are joining The New Normal family," Murphy tweeted.

The show centers around a gay couple (played by Andrew Rannells and Justin Bartha), who have successful careers but want a baby. Goldie (Georgia King) agrees to be their surrogate, to the dismay of her cantankerous grandmother Jane (played by Ellen Barkin).

Their roles and starting dates are not yet available.

Takei recently appeared on “The Celebrity Apprentice.”  Richie appeared as her spoiled, vapid, rich girl self in “The Simple Life” with Paris Hilton, and also does something involving fashion.

Bartha appeared in the “Hangover” movies, and Rannells was in “The Book of Mormon,” a Broadway play created by the creators of South Park.

“The New Normal” had 6.9 million viewers on its Sept. 10 debut.

The show airs on NBC at 9:30 p.m. Tuesdays.
