Newly Single Heidi Klum Rocks Revealing Dress At Hollywood Event

Heidi Klum may be a single lady, but she's not at home moping around about it. The stunner attended Reese Witherspoon and Jim Toth's Hollywood Stands Up to Cancer event Tuesday night (Jan. 28) and looked incredible on the red carpet in a high-slit, low-cut number.

The 40-year-old arrived solo at Book Bindery in Culver, Calif., looking sexy as ever in a chocolate brown, leather-belted frock by Michael Kors. Jamie Foxx, Zooey Deschanel, Gwyneth Paltrow and Jessica Alba were among the famous faces there to mingle and do good.

Earlier in the week, news broke that Klum and her boyfriend of 18 months, bodyguard Martin Kirsten, are no longer an item.
