There's no better revenge than looking super-hot after a breakup and that is exactly what Heidi Klum did Tuesday night at the Hollywood Stands Up For Cancer event. The super model looked stunning in a plunging brown dress! And she wasn't the only lady to rock the red carpet. Reese Witherspoon and Selena Gomez also took the plunge in super low-cut looks, love it! And Gwyneth Paltrow showed off her rock hard body in a cobalt blue cut-out dress! Check out our favorite looks from the event here!
