During what was his first outing since announcing his split from Pearlman, 64, DeVito happily flashed a thumbs-up sign to well-wishers.

Married to Cheers alum Pearlman since 1982, DeVito -- who confirmed their split though his rep on Oct. 8 -- once said the couple's recipe for an enduring relationship was simple. "Love. I mean, really. [But] you know what? Who knows," the actor has said. "The secret to success is to try to never figure that out."

Pearlman -- who has guest-starred in Hot in Cleveland, The Sessions and Wilfred in recent years -- and her ex have three adult children together: Lucy, 29, Grace, 25, and Jacob, 25.
