  On July 9, 2007, Nielsen checked herself into the Cri-Help rehabilitation facility in North Hollywood following what some reports claim was a family intervention. Her manager, Steven Tempone, confirmed on 19 July 2007 that she had checked into a rehabilitation center and said, "All I know is it's something she did of her own free will and we're proud of her and wish her very well... When she gets out we'll have a big birthday party, and Coca-Cola only." As of 22 July 2007, Nielsen was out of rehabilitation to attend the Comedy Central roast of Flavor Flav. She remarked that she felt "like a new-born person ... I made a choice about a new life. It's not been easy but it was definitely time." While the date that Nielsen checked into rehabilitation was reported, she "had been in treatment for a few weeks." On January 10, 2008, VH1 began airing the reality TV series Celebrity Rehab. Nielsen appeared on the show for alcoholism. In a January 2010, TV Guide story on her success with sobriety, Celebrity Rehab producer John Irwin stated, "She's sober, and she quit smoking."
