Oksana Grigorieva performed live in Hollywood last night and while the place was packed, Oksana's performance was ... well you can listen for yourself.

Oksana played the Gardenia Lounge in West Hollywood last night as she tried to further the singing career that was once helmed by ex-boyfriend Mel Gibson. He was her executive producer at one point and when they split, securing the rights to her music was Oksana's mission.

As for the show, our guy inside said the place was quite crowded and everyone was there specifically to see Oksana.

Afterwards, she told our guy the show went well.
