Justin Timberlake and Ashton Kutcher are keeping busy outside of Hollywood. Both celebrities signed on for new Internet gigs Wednesday.

Timberlake, who played Internet music-sharing pioneer Sean Parker in The Social Network, is taking an ownership role in MySpace, The Wrap reports. The 30-year-old will help develop the social networking site's creative direction and strategy.

"There's a need for a place where fans can go to interact with their favorite entertainers, listen to music, watch videos, share and discover cool stuff and just connect. Myspace has the potential to be that place," Timberlake said in a statement. "Art is inspired by people and vice versa, so there's a natural social component to entertainment. I'm excited to help revitalize Myspace by using its social media platform to bring artists and fans together in one community."

Kutcher, who became the first Twitter user to reach 1 million followers, is joining sports website SB Nation's board of advisors. The site's chairman and CEO Jim Bankoff announced Kutcher's involvement, calling him  "a sports and gadget fan with great ideas."

Kutcher has already started brainstorming partnerships and recruiting talent for the site, a source tells BusinessInsider.com.

This hardly means the two are leaving their day jobs just yet. Timberlake will next appear on the big screen in Friends with Benefits (opposite Kutcher's former That '70s Show castmate Mila Kunis). Kutcher will return to TV this fall when he replaces Charlie Sheen on Two and a Half Men.
