Eat your heart out, Martin Kirsten.

Just one day after E! News confirmed that Heidi Klum and her bodyguard beau had ended their personal and professional relationship, the supermodel returned to the red carpet on Tuesday, Jan. 28. Klum—who is still legally married to Seal—looked sexy and confident as ever in a plunging Michael Kors dress with a thigh-high slit. She cinched her waist with an oversized belt and accessorized with gold jewelry and Fariha sandals.

Klum has yet to address her breakup with Kirsten, whom she began dating a year and a half ago. "Martin was there for her during a challenging time in her life and it was something she will always be grateful for," a friend close to Klum told People. "Life is about timing. He was incredibly supportive and they were there for each other, but they're moving on now. They still have a great friendship."

The Hollywood Stands Up to Cancer benefit was presented by the Entertainment Industry Foundation and chaired by Reese Witherspoon and Jim Toth. Conan O'Brien emceed the star-studded event, which featured special performances by Christina Aguilera, Jamie Foxx and John Mayer.
