Tonight VH1′s “Celebrity Fit Club,” — where a Marine DI whips B- and C-list celebrities back into shape — is back for the seventh season.

According to a review from the New York Daily News, this group includes Shar Jackson from “Moesha“; Bobby Brown from the Whitney Houston marriage; Tanisha Thomas from “Bad Girls Club“; and Kevin Federline from the Britney Spears marriage.

Extra credit for any viewer who notices that Federline and Jackson have the added connection of being parents of the same baby.

That situation, which one imagines was hardly incidental to the casting staff, surfaces briefly tonight and apparently will get its whole dramatic moment further along in the nine-episode series.

Bobby Brown gets Monday’s highlight-reel moment.

The other celebs look at the relatively spare surroundings in which they will live during the show and start muttering about barracks.

Brown looks around, shrugs, and says, “It’s easy compared to being in jail.”

Retired Marine DI Harvey Walden 4th does his part to make this experience look as harrowing as possible, though, as in past seasons, it becomes clear that his power is limited.

But then, “Fit Club” isn’t out to teach the country a fitness regimen. Its main goal is to stir up some passing celebrity dust.
