Brit Beauties: Keira Knightley + Sienna Miller

Keira Knightley and Sienna Miller have 3 major things in common at this moment: both Brits, both beautiful, and both currently starring in theatrical plays in London Town.

Heading out after a night of performing in her latest theatrical effort, “Flare Path”, Sienna was spotted leaving the Theatre Royal Haymarket in London tonight looking flirty and cheerful in a flouncy floral mini and ankle boots. Simultaneously, Keira posed outside of London’s Comedy Theatre after another performance in ”The Children’s Hour,” looking frigid in a librarian-esque getup.  Looks can be deceiving, though, as we know Keira ain’t so uptight after pics surfaced earlier this week of her making out with her new boyfriend James Righto (of the Klaxons).

Which look do you prefer – poised or floosy?
