Benedict Cumberbatch Flies Solo On The Red Carpet

Even though he's recently engaged, Benedict Cumberbatch doesn't mind hitting up the red carpet without a date.

The 38-year-old actor, who announced his engagement to theatre director Sophie Hunter last week, flew solo at the L.A. premiere of his film "The Imitation Game" on Monday.

For the occasion, the "Sherlock" star was his usual stylish self in a dark grey suit that matched his serious gaze. Co-star Keira Knightley also attended the premiere (although the twosome didn't pose together) wearing a gorgeous white embroidered Chanel Couture dress that was similar to a Chanel Lupita Nyong'o wore to the Glamour Women of the Year event, also on Monday night.

Benedict has been showing off his sartorial savvy during "The Imitation Game" press tour the past week. Looks have included classic black-and-white suits and natty burgundy three-pieces.

Hello, gorgeous:
