The reasons for Donna Martin's longtime status as a virgin on Beverly Hills, 90210 are finally being spelled out for its star.

On the latest episode of the 9021OMG podcast, host Tori Spelling, who played Donna for all 10 seasons of the popular series from 1990-2000, put producer and writer Charles Rosin on the hot seat about where the character arc originated.

Rosin broached the topic first, reminiscing about a time when Spelling's father and series producer Aaron Spelling told him "that Donna should be a virgin." "And it was like, 'Yes, absolutely she should,'" Rosin recalled thinking.
