The audience at Lily Allen’s Hollywood show last night were treated to the bizarre sight of Lindsay Lohan stumbling on stage during the singer’s rendition of Britney Spears’ Womanizer.

The Smile star had almost finished the song when the actress appeared seemingly from nowhere, gave Lily a hug, sang a couple of words into her microphone and then threw some awkward diversion moves.

It’s not known whether the pair – who hooked up when Lily was in the US last year – had planned their nano-duet but Lily appeared to largely ignore her friend, leaving Lindsay to hang around sheepishly at the back of the stage for a few seconds before disappearing off from wence she came.
