Michelle Williams may be getting over a breakup, but you'd never know it from looking at her! In the few days since Us Weekly broke the news of the actress' split from How I Met Your Mother star Jason Segel, whom she dated for a year, Williams, 32, has been as composed and stylish as ever during European promotions for her new flick, Oz the Great and Powerful.

Posing with co-stars Mila Kunis and James Franco at a Feb. 27 photo call and press conference in Russia for the epic fantasy, in theaters March 8, the Dawson's Creek alum was all smiles in a black sleeveless Victoria Beckham minidress that showed off her slim, sexy legs. She paired the tres chic frock with black Charlotte Olympia heels embellished with tiny stars.

Later that same night, Williams traded the sweet sheath for a dress with a little more drama. Walking the green carpet at the Okyabe Cinema Hall in Moscow, Russia, the Oscar-nominated actress sparkled in a super-glam gown by designer Jason Wu, with black-and-gold chevron stripes running down the length of the frock. Christian Louboutin shoes and a gold Verdura cuff completed the ensemble.

One day later, at the London premiere on Thursday, Feb. 28, the blonde beauty -- and mom to 7-year-old Matilda, her daughter with the late Heath Ledger -- rocked a blue strapless Burberry Prorsum frock with all-over feather detailing. She accessorized the look with black Jimmy Choo sandals, a black clutch, and a green Solange Azagury-Partridge ring.
