Celebrity reality shows are one the great train wrecks of current pop culture. If the subjects aren’t simply celebrity has-beens from long-gone eras, they are those who have continued to hang by their fingernails onto their need to be famous.

VH1’s Celebrity Fit Club 7 (wow, there were six others?!) parades out a few stars of yesteryear (Bobby Brown, Sebastian Bach of Skid Row, Nicole Eggert of Baywatch). But. Then there are those people who are famous for being on a different TV show, which by today’s standards makes you a star! That’s right, people like Tanisha Thomas and Jay McCarroll are now career reality TV personalities. Hey, it’s a living I guess.

Kevin Federline, Britney Spears‘ ex-husband, is joining the seventh season of VH1’s Celebrity Fit Club. Federline has packed on some pounds since his split from Spears. Joining him on the cast will be his former girlfriend and mother of two of his children, Shar Jackson. Other reported contestants are Baywatch star Nicole Eggert and Whitney Houston’s ex, Bobby Brown.

Celebrity Fit Club features stars who have had their time in the limelight come and gone. They vie for cash and prizes as they sweat and diet to reclaim their former slimmer bodies.

First it was his ex-wife, Britney Spears is forever being pounded and hounded by the media; now Kevin Federline has the spotlight shining on him for his ever-expanding size.

Once a back-up dancer for Micheal Jackson, Justin Timberlake and Gwen Stefani, K-Fed used to sport a well-toned and fit physique. But perhaps it is the constant pressure of being mobbed by paparazzi, the agonizing battle over the custody of his two sons or his role as a full-time parent, Kevin has gained considerable weight in the past few months.
