While the US was enthralled with the Grammy Awards last eve, across the pond, there was another celebration going on - the BAFTA Awards.

And like any good celebrity-laden event, there was an afterparty. Stars like Keira Knightley and Sienna Miller (with her sweetie Rhys Ifans) showed up to hob nob with fellow winners and nominees.

The “Pirates of the Caribbean” actress showed up to London, England’s Grosvenor House for the festivities in a strapless, multi-tiered silver gown, and a all-down curly coif.

And Sienna and Rhys looked ever-so-happy together, both sporting similar black ensembles, with the “Factory Girl” actress in a satin gown, and her musician arm candy sporting a black suit with a white button-down shirt and black tie.

Other attendees included Cuba Gooding Jr., Orlando Bloom, Anthony Hopkins, Kate Hudon, and Marion Cotillard.
