Ashton Kutcher walked the red carpet solo at Monday's premiere of New Year's Eve at iconic Grauman's Chinese Theatre in Hollywood, marking his first major Tinseltown outing in the wake of the announcement he and Demi Moore would be divorcing.

The clean-shaven Two and a Half Men star, 33, wore a grey suit with a yellow tie to the first showing of the Garry Marshall-directed ensemble film, which also features two of show biz’s hottest young stars in Glee stunner Lea Michele and High School Musical hunk Zac Efron.

Others in attendance at the star-studded premiere included Ryan Seacrest, Michelle Pfeiffer, Josh Duhamel and wife Fergie, Hilary Swank, Katherine Heigl, Sofia Vergara, and Michelle’s Glee co-stars Cory Monteith, Chris Colfer and Harry Shum Jr., among others.
