A Michigan couple convicted of attempting to extort $680,000 from actor John Stamos were both sentenced to four years in prison on Friday, according to the Associated Press. Allison Coss, 24, and Scott Sippola, 31, were convicted in July of conspiracy and using e-mail to threaten a person’s reputation after threatening to sell old photos of Stamos with strippers and cocaine to the tabloids unless he paid them to keep quiet. The FBI said the photos did not exist. Stamos reportedly met Coss in Orlando, Fla., in 2004 when she was 17 years old, shortly after separating from his wife, model-turned-actress Rebecca Romijn. Coss testified that Stamos snorted cocaine, sat nude in a hot tub with the teenager, and made sexual advances. Stamos denied her account, calling the couple’s allegations “reprehensible” in a statement. “The defendants’ strategy consisted of lying and inventing stories at trial in a bid to confuse and incite the jury,” the Full House star, 47, wrote. “I was forced to watch [Coss] slander me at trial with impunity while the press reported their fabricated allegations.”
