If you've watched TV in the last few weeks, you're certain to have seen the Gwen Stefani endorsed HP commerials being broadcast.

Gwen and HP teamed up at the beginning of her "The Sweet Escape" World Tour as HP was a major sponsor.

The tour may have ended, but the memories are still available(to buy).

Head over to HP's Gwen Stefani section of their website.

There you can make stationary and other cool Gwen inspired art.

Also, you can purchase  Gwen's "Sweet Escape" Tour Book, which is becoming quite rare to find nowadays.

Gwen didn't sell the tour book until midway through the tour, as she wanted to fill it with performance photos of her in action.

Also, a friend sent me over these photos of a massive billboard campaign in Las Vegas for the HP products.
