Application discovery engine Chomp now has some serious star power in its corner. The SV Angel-backed company is today announcing that Hollywood technophile Ashton Kutcher has signed on as an advisor to the company.

Kutcher joins Kevin Rose, creator of Digg, as Chomp's second advisor. The two will help the startup build relationships, as well as contribute to the company's product and marketing strategies.

Chomp exists as a web service and iPhone application [iTunes link]. The startup tackles application discovery by providing search, personalized recommendations and highlighting friends' applications.

Kutcher is fast becoming an important mover and shaker in the technology sector as both startup advisor and angel investor. Some of Kutcher's investments include Flipboard and Hipmunk.
