Reports and rumors have been rampant since news of the split first broke on Friday, speculating about whether Cruise's ties to the Church of Scientology played a role in the breakup and what the split will mean for the couple's 6-year-old daughter Suri (TMZ reports that Holmes is seeking sole legal custody).

Holmes, meanwhile, stepped out Monday - without her wedding ring, media outlets noted - to tape a guest appearance on "Project Runway: All Stars" in New York.
