Nearly 40,000 people dressed in colorful costumes attended this year’s Life Ball, Vienna’s glitzy annual AIDS charity, Saturday, with actress Milla Jovovich and former U.S. president Bill Clinton among those adding to the star factor. It’s the high profile event where fashionistas don their brightest colours to help raise money for a good cause, and it took place in Vienna’s city hall on May 19, 2012. Milla had the right idea for how to stand out amongst a sea of glitzy celebrities when she made her outfit choice for the 20th Life Ball. Wearing a lime green Atelier Versace gown, the 36-year-old model and actress employed two tactics as a means to be the brightest star of them all, stepping out in neon while also flashing ample flesh.

Of meeting Clinton, Milla tweeted: “It’s so incredible at the #LIFEBALL! I had the privilege of meeting our former pres. Clinton! He is doing so much 2 help fund medicines 2 reach children in 3rd world countries working with an unbelievable woman named catherine tucker who has an orphanage in Cambodia. They save children’s lives every single day. What a honor to meet the real heroes. Lol! It’s a bit blurry but finally here is a pic of bill Clinton n I! I already have one with Hillary, so my collection is complete!”
