Guy Ritchie's absence from Madonna's induction into the Rock and Roll Hall of Fame Monday did little to quash rumors of marital strife between the couple.

The Ritchies have been noticeably absent from each other's events lately, and haven't been photographed together in public since January.

But Monday wasn't just any night for Madonna. So ... where the heck was Guy?

Madge's publicist, Liz Rosenberg, told us yesterday that Ritchie was 'making a film in London' during his wife's big moment. "They spoke right after her induction via phone," she added.

According to IMDB.com, Ritchie's latest film, "RocknRolla," is categorized as "completed." He has no other projects in the works, per the online movie database.
