Fit Fifty Cent.
Who doesn’t want to drop a couple of pounds after binging over the holidays? But among the many lifestyle guides out there, would you consider taking fitness advice from 50 Cent? The 11-time Grammy nominated-rapper, whose real name is Curtis James Jackson III, has reportedly released his first fitness book, Formula 50, with co-author and health journalist Jeff O’Connell. On a recent appearance on the “Today Show,” Jackson revealed how his severe gunshot injuries in 2000 inspired him to rebuild his physical strength in addition to balancing his monetary wealth. Jackson, who enjoyed overnight success with this debut album, Get Rich or Die Tryin’ in 2003, is often featured showing off his chiseled chest, biceps and six-pack abs in promotional material and his music videos. His fitness formula in the book details how he achieved his ripped physique and, with the help of several bodybuilding experts, outlines the benefits of a protein-rich diet plan and metabolic resistance training (MRT) – which focuses on rapid fat loss through shorter, more intense workouts. Check out 50 Cent’s book promo for Formula 50.

According to Deadline, the show will air in a half-hour format and will be executive produced by Simpson, “Two and a Half Men” scriptwriter Nick Bakay, “Fashion Star” reality series producer Ben Silverman and Simpson’s father/manager Joe Simpson. “Jessica Simpson is truly a modern-day Lucy with incredible comedic chops,” says Silverman. Simpson, who once guest starred on “That ’70s Show,” added that, “I often find myself thinking that no one could ever make up the things that actually happen in my life — so between the real-life elements and a great team of writers, I think we’ll have people laughing!” The singer and television personality recently announced that she is expecting her second child with fiancé Eric Johnson and, has also reportedly decided to expand her maternity fashion line due to high demand.

Russell Crowe still single.
While the image of Russell Crowe and Dita Von Teese together may be titillating, surprise, surprise…it’s not true! Fresh from a reported holiday reunion of sorts with his children and estranged wife Danielle Spencer in Sydney, Australia, Crowe has come out via Twitter to deny rumors that he’s dating the burlesque star and lingerie model. According to the New York Post, the Broken City actor – who is also enjoying the award-winning success of his critically acclaimed film Les Misérables – and Von Teese had booked an intimate couples massage at the Four Seasons Hotel in New York last month, which they allegedly followed with some flirting via Twitter. But there’s no romance here, as Crowe who may be alone in love, is certainly not lonely for new friends – intimate couples massage or not.

Diff’rent Strokes star passes.
Actor Conrad Bain has died at the age of 89. Bain’s role as millionaire businessman Phillip Drummond and father figure to his fictional daughter Kimberly, played by the late Dana Plato and sons Willis and Arnold Jackson, played by Todd Bridges and the late Gary Coleman lasted for eight seasons from 1978 to 1986 on the sitcom “Diff’rent Strokes.” A saddened Bridges reportedly made a statement to TMZ saying, “In addition to being a positive and supportive father figure both on and off-screen, Conrad was well-loved and made going to work each day enjoyable for all of us. He will be missed, but never forgotten.” While Plato, Coleman and Bridges reportedly led troubled lives punctuated by arrests, substance abuse, anger management and illness, Bain appeared to live a relatively peaceful life before passing away of natural causes at a retirement home in Livermore, CA on Monday according to TMZ. He leaves behind three children and a brother.
