tom cruise jack reacher premiere 2012 gi Tom Cruise single and smiling at 'Jack Reacher' London premiereTom Cruise is about to embark on a media blitz for his new action movie “Jack Reacher,” and if attending the film’s London premiere solo was a concern for the recently divorced star, he wasn’t showing it.

Although he split from third wife Katie Holmes in July, Cruise’s trademark smile was in full force on the red carpet for “Reacher.”

The premiere drew co-stars Rosamund Pike, Robert Duvall and David Oyelowo, plus celebrity guests including Nicole Scherzinger (with boyfriend Lewis Hamilton) and Tom Hardy.

Holmes has been starring in the Broadway play “Dead Accounts” but this was Cruise’s first appearance at a red carpet event since they separated. He’s been busy filming the sci-fi thriller “Oblivion,” due to open next year.

“Jack Reacher” opens Dec. 21 in the U.S.
