Reese Witherspoon's Almost Loveless Evening With Hubby

Find out what the Oscar Winner was up to last night, plus more star sightings with Kourtney Kardashian, Glee star Mark Salling and mommy-to-be Hilary Duff

Reese Witherspoon is still a little black-and-blue from her running mishap with a car, but that didn't stop her from stepping out last night to support hubby Jim Toth.

The Oscar winner was one the many celebs at the Toth-hosted Art Mère/Art Père art auction benefit for Livestrong.

But it almost turned into a loveless evening for Ms. Witherspoon...

Don't worry, all is good on the home front. Witherspoon got into a bidding war for a photo of signage from the Loveless Motel, a famed landmark in her native Nashville.

While she lost on that item, she did go pick up a painting of multiple American flags by artist Jeff Cahill for $1,600.

Also at the event were Matthew McConaughey and Camila Alves, enjoying the Fatburger truck and drinks from Corzo tequila; Johnny Galecki, checking out the bright yellow Ferrari Italia 458 on display next to the red carpet; and Sanaa Lathan, hitting the JetBlue kiosk.

Eli Roth was there. The Inglourious Basterds star's artist mom, Cora Roth, donated a mixed media work called Pink Light to the auction. "I'm her plus-one tonight," Eli smiled.

In other star sightings...

Mark Salling, Jessica Alba, Chris Evans, Adam Brody, Jamie Kennedy and Dane Cook helped nightlife impresario Darren Dzienciol celebrate his birthday at the Beverly in West Hollywood.

E!'s own Giuliana Rancic hosted last night's UCLA Department of Neurosurgery's Visionary Ball.

Mommy-to-be Hilary Duff relaxed with a mani-pedi at the Nail Garden in Burbank.
