KEIRA KNIGHTLEY hits bar after split from longtime boyfriend RUPERT FRIEND

British actress KEIRA KNIGHTLEY sang away her blues following her split from longtime boyfriend RUPERT FRIEND by hitting a karaoke bar with SIENNA MILLER and a group of pals on Thursday night (13Jan11).
The couple, which met on the set of 2005 movie Pride & Prejudice, decided to end its five-year relationship shortly before Christmas (25Dec10), according to the actress' father Will.
But Knightley has refused to wallow in self-pity at home, and hit the streets of London for a night of sing-along fun with friends, including her The Edge of Love co-star Miller.
The group showed off their vocal skills on tracks such as Queen's Don't Stop Me Now and Bon Jovi's Livin' On A Prayer while drinking Cosmopolitan cocktails at the Lucky Voice karaoke bar, according to Britain's The Sun.
A source tells the newspaper, "It was a pretty raucous affair. The girls went really crazy for Cosmopolitans. They weren't holding back at all.
"There were about 12 people in the group, but no diva-like antics. They all got stuck in (involved)."
