Allen performed Brit Brit's "Womanizer" for the crowd at her L.A. concert -- and Lohan jumped up on stage to flail her arms around and attempt to sing alongside her. Spears would be proud.

One of the posters here is right... Lily (or whatever her name is) has absolutely NO stage presence OR energy. Don't tell me I wasn't at the show and I don't know. For the last several years I live and breathe music showbiz and I know what it takes since I actually have the experience to back up what I say! And yes, it was very embarrassing when Lily gets closer to Lohan with the mic and just as Loblow is about to sing with her she PULLS AWAY!!! How DEGRADING!! In front of a crowd! She owns her now.
Lily allen (who doesn't have a bit of talent) singing a song that another no-talent hack (SLUTney spears) put out, accompanied by the ultimate no-talent hack (WHOREhan)? Who the hell would pay for such a mess? I guess it doesn't take talent to get onstage nowadays; all you have to do is snatchflash or nippleslip...
As someone who was actually THERE, Lily was amazing all night. I could care less if Lindsay attention whore got on stage or not. They are friends so it's their deal. I like a couple songs Lily does and she impressed me with her vocals and was very kind and interactive with the audience. And it was sold out. The entire crowd was into it.
Lindsey the Lez Lohan. Hey Lezzie.....when your head is between Sam's thighs, god is looking at the back of it.
i was there last night and the show was going amazing well until this s**! happened. i paied to see lily do her thang not lohan shake her bones. Thier interaction was quite akward. lol but i loved it.
WOW, TRULY PATHETIC!! You have one trainwreck dancing for another trainwreck singing for yet another trainwreck. HAHAHA! All three chicks should do the world a favor and mix each others prescription pills.
Looked like Lily was about to pass out till Lohan came out there and pumpt her up along with the Audience.
Britney Spears might miss a lot more 'X Factor' auditions ... because she can! Simon Cowell gave Brit damn near free reign in order to sign the pop star to that $15 million deal -- but is it backfiring? We'll tell you what peeps on the set are saying.Plus, Chris Jericho's…
