Last we heard, they were planning on moving to Vancouver together for J2's show Fringe, but looks like they still need some necessities for their L.A. pad. We totally love that Josh and Diane are hands-on with their home and don't just throw money at somebody to fix the job for them. Way to save in this crap economy, you two—not like ya really need to.
Other clothes-minded celebs putting their credit cards to good use were...
Kevin James, shopping at the Prudential Center in Boston. The funnyman, who's in town filming the Adam Sandler flick The Zookeeper, wore a black tee, hat, jogging pants. He was talking on his iPhone, shopping alone, we bet because no one can forgive him for making Paul Blart: Mall Cop.
A much, much sexier dude—who doesn't wear ratty jogging pants while out in public, or prolly ever—inhabiting the exact same spot was...
Steven Tyler, hanging with some hometown pals in the popular Beantown shopping mall. Guess Stevie's feeling tons better after his nasty fall at a gig, forcing him to cancel the rest of Aerosmith's tour. Nothing like retail therapy, right?
The Aerosmith frontman "looked like himself" says our source, so we're guessing skinny pants, flamboyant shirt, and handkerchief, right-o?
Our Bahstin eyes couldn't believe a schlub like Kevin James and a rock god like Steven hang in the same place, though we think Kevin is certainly more in need of a shopping spree for a new wardrobe.
