The show originally was developed as a pilot for NBC, which passed before VH1 picked it up.
"It's our biggest project from a cost perspective," said Michael Hirschorn, VH1's newly appointed executive VP original programing and production. "But it seemed like the next logical step for the network, so it was a risk we were happy to take."
For her part, Spelling said her family calls her "brave" for taking a role in which she often pokes fun at herself.
VH1 unveiled its slate during parent company MTV Networks' portion of the Television Critics Assn. press tour in Pasadena Wednesday.
Hirschorn, a former music journalist who joined VH1 in 2001, said he intends to continue doing "celeb-reality" shows such as "Hogan Knows Best" and "Celebrity Fit Club," but he also wants to focus on developing music-oriented programing.
"VH1 has always been about music, but we've had so much success with 'celeb-reality' at times that the fact we have a music background has been skewed," said Hirschorn.
One example of that was on display Wednesday in the form of "Heavy: The Story of Metal," a four-part documentary premiering at 9 p.m. May 1. The documentary will be in similar to VH1's 2004 hip-hop chronicle "And You Don't Stop" and will feature interviews with musicians, promoters, writers and fans.
