This week on 'Celebrity Apprentice' (Sun., 9PM ET on NBC), while one contestant left the show, another came back, as a delayed replacement for Jose Canseco, who quit. This week featured a lot of fighting between Star Jones and NeNe Leakes, but then again that's not really anything new.

!!SPOILER ALERT!!

At the challenge, teams had to produce a show to promote Farouk Systems hair care products, emphasizing their safety and that they are made in America. Lil Jon was project leader for the men, who brought in eliminated contestant Niki Taylor to help them out by being gorgeous and having gorgeous hair, and she did just that.

She's Playmate of the Year 2010 and she's a runway model, but who is Hope Dworaczyk really? Well, she can now be seen on our TVs each week as the one not getting in huge catfights on Donald Trump's 'Celebrity Apprentice.'

Competing alongside the likes of Gary Busey, Marlee Matlin, LaToya Jackson, rapper Lil John, 'Real Housewives of Atlanta' star NeNe Leakes and Star Jones, Dworaczyk is raising money for Best Buddies, an organization designed to provide mentoring and employment for those with intellectual and developmental disabilities.

But we all know that Trump's cutthroat competition (Sundays, 9PM ET on NBC) doesn't always mean rainbows, butterflies and the joy of helping people -- and this season looks more aggression-filled than ever.

I caught up with Dworaczyk (pronounced "dor-AH-sik") to get the real scoop on this drama-packed season, including those nasty fights between NeNe and Star, the benefits of playing nice, a very meaty challenge and the celebrity she calls "so crazy!"

Though the roster for the next 'Celebrity Apprentice' was leaked in October, Donald Trump made the official announcement on 'Late Night' (weeknights, 12:37AM ET on NBC).

He brought along 8x10s of each cast member, and Jimmy Fallon unveiled them one by one: LaToya Jackson, Gary Busey, Star Jones, Atlanta's 'Real' Housewife Nene Leakes, baseball's José Canseco, Lisa Rinna, former teen idol David Cassidy, supermodel Niki Taylor, 'Survivor' Season 1 nudist/winner Richard Hatch, Oscar winner Marlee Matlin, Meat Loaf, Mark McGrath, Playboy Playmate Hope Dworaczyk, Lil Jon, Dionne Warwick and country music's John Rich.
