Whereabouts: Demi & Ashton Jonesing for Joan’s

Ashton Kutcher and Demi Moore managed to focus on something aside from their star-studded private Oscars bash with Madonna over the weekend.

On Saturday morning Celebuzz spies caught the couple at popular Los Angeles eatery Joan’s On Third. Draped in a soupy brown sweater, oversized sunglasses and ballet flats, Demi enjoyed breakfast with her younger hubby, who sported a white baseball cap and button-up for the occasion.

Don’t feel bad for Rumer and her sisters, however; the onlooker tells us the pair got cupcakes and danish to-go, then hopped in their Prius and took off.

Another errand-runner pre-Oscars was Justin Timberlake’s gal-pal Jessica Biel. She was caught by a Celebuzz source nabbing organic dog food at West Hollywood’s Petco, for her pitbull Tina.

Also on Saturday, model Amber Valetta turned out for Tag The World’s Los Angeles launch at Hollywood club MyHouse. The charity raises awareness and funds in conjunction with the American Humane Society and other organizations.
