Betty White, who guest starred on Bones last season, will reprise her role as Dr. Beth Mayer in the upcoming 12th season, Deadline reports.

White will reportedly appear in the tenth episode of Bones' final season. She first appeared last year as Dr. Beth Mayer, the world's most experienced forensic anthropologist (get it? she's old), helping Brennan (Emily Deschanel) and Booth (David Boreanaz) solve a murder, which presumably she will do again.

Bones' upcoming 12th and final season will bring back many old favorite guest stars, so Betty White is likely the first of what's sure to be a slew of Bones guest stars to come.
