Lily Allen was joined on stage in Los Angeles last night by a very special guest, Lindsay Lohan.

Lohan bounded onto the Wiltern Theatre stage towards the end of Lily's rendition of the Britney Spears track 'Womanizer' and hugged the singer.

The crowd cheered before the actress did a awkward dance and swiftly disappeared. You can see the video below - skip to 3.30mins for Lohan's entrance.

Lily Allen's 14-date North American tour continues tomorrow night at The Warfield in San Francisco and closes with a show at the Phoenix Concert Theatre in Toronto on April 22.
