Longtime Saturday Night Live heavy hitter Kristen Wiig last night added another role to her seemingly limitless repertoire: That of SNL alum. The seven-year veteran bid farewell in a not-so-successful attempt at concealing tears as guest host Mick Jagger brought her up in the show's final sketch, a commencement, in which he introduced "one particular student who is leaving this summer." Wiig tearfully danced with Jagger, various cast members, producer Lorne Michaels, and even Steve Martin to the Rolling Stones' hit, "Ruby Tuesday," mouthing the line, "I'm gonna miss you." Wiig's departure is far from surprising, but there was no word on Andy Samberg and Jason Sudeikis, both of whom are also rumored to be leaving the show. Michaels recently said that cast changes will wait til summer, notes the AP. (More Kristen Wiig stories.)
