These ladies are in deep doodoo!

Even celebrities take a wrong turn sometimes and occasionally is a REALLY wrong turn. First off, Felicity Huffman paid $15,000 to have some dude cheat her daughter's SAT score to boost it 400 points to a 1420. So now she's pleaded guilty to fraud, along with 13 other parents and one former university coach in this huge college admissions scandal case. The Desperate Housewives alum, 56, faced a whopping TWENTY years in prison for scamming her daughter's way in to college.

Huffman released this statement today, when entering her guilty plea: "I am pleading guilty to the charge brought against me by the United States Attorney’s Office. I am in full acceptance of my guilt, and with deep regret and shame over what I have done, I accept full responsibility for my actions and will accept the consequences that stem from those actions. I am ashamed of the pain I have caused my daughter, my family, my friends, my colleagues and the educational community."

Meanwhile, a fellow actress, Allison Mack who appeared on the hit Smallville broke the law in a decidedly different way ... she's pleaded guilty of sex trafficking in the NXIVM sex cult case. The star was indicted on multiple counts of sex-trafficking, sex-trafficking conspiracy and conspiracy to commit forced labor in the case after allegedly recruiting women to be sex slaves for cult leader Keith Raniere. She was also accused of identity fraud and money laundering for the cult based in upstate New York.

Mack was arrested almost a year ago and release on $5 million bail -- at the time, she pleaded not guilty to all charges. But when the cult's co-founder's daughter pleaded guilty, Mack changed her tune. And what a tune it is -- listen to what she's guilty of ... court papers say Mack would "have victims provide the group with naked photographs, assets, criminal confessions and other damaging information, known as collateral." And it gets worse: "Mack would perform ceremonies in which her slaves were branded … [She] would place her hands on the slaves’ chests and told them to ‘feel the pain’ and to ‘think of their master,’ as slaves cried in pain."

Okaaaaayyyyy. Mack supposedly tried to recruit Emma Watson and Kelly Clarkson via Twitter (stay away, ladies!). She faces up to 40 years in prison and will be sentenced September 11.
