Lindsay Lohan
In may (before Sienna and Jude announced they were back together again) Lindsay Lohan kept the lovebirds company in their V.I.P. booth, and even
volunteered to head outside first at the end of the night, creating a flashbulb frenzy that prevented photographers from catching on to the comely duo.

Victoria Beckham
Sienna was introduced to Victoria by Elton John's partner David Furnish. Victoria is reported to have cheekily introduced herself to the actress by saying, "it's nice to meet someone who's almost as unpopular as me." It broke the ice and they spent the entire evening together gossiping. The two girls swapped numbers and have met up since the party. Now they are planning a break away together. One thing both Sienna and Victoria allegedly have in common is that they both hate football.

Tamara Summers
Tamara can be seen kissing on Sienna's toes in the 2006 may issue of Vanity Fair. That's friendship!

Susan Sarandon

The people listed below are rumoured to not be on such good terms with Sienna...

Kelly Osbourne
After Sienna announced she wanted to take legal actions against the paparazzi stalking her Kelly was sure to give her opinion; "It's what you get - I mean, don't be famous if you don't want it. Don't spill your beans to everyone, and don't be famous if you don't want some attention. In some ways, I feel sorry for her, because she has had a lot of trouble, but - come on - you choose to be a celebrity, it's part of the job."

Kate Moss
Kate is reportedly mad at Sienna because she is getting Kate's magazine covers. She said Sienna is "only an actress and not a professional model"

Elizabeth Hurley
After Sienna went and cut her hair short in 2005 Elizabeth was quoted "That's the thing about valuing trends above sexiness," she told reporters, "It exposes your flaws. That cut exposes the poor girl."
