After a weekend filled with rumors that Saturday Night Live star Kristen Wiig would be leaving, the actress said Monday that her future at the late-night staple is uncertain. Wiig, whose contract is up this year, said “I don’t know” when Alec Baldwin asked her during an interview if her time at the show is “winding down.” “Everyone has to leave … and I will say that when I do leave, it’s not because I’m sick of it and not because I see something better or anything like that,” she said. “It’s just time.”
