is making a public statement about her split from Tom Cruise
: She's no longer wearing her wedding ring.
The actress, 33, who filed for divorce
from the movie star, 49, on Friday, shot a Project Runway: All Stars segment
on Monday sans the ring that Cruise gave her more than five years ago.
Holmes – who was said to have done "great" at the taping despite her personal drama – left Cruise "devastated and heartbroken," a source told PEOPLE
of the breakup. "He had no idea this was coming."
The pair wed in an Italian castle in November 2006.
