The 'Octomom' checked into a treatment centre on Monday (October 29) for a dependency on the prescription medication Xanax.
Michael, the father of Lindsay Lohan, has now disclosed to TMZ that he and Suleman's handlers organised an intervention to ensure that she sought help for her alleged addiction.
"The most important thing is the willingness to realise and surrender to the issue and commit to getting help, which Nadya did," Michael told the website.
He added: "If it wasn't for her manager Gina, my good friend, Tim Chapman at the Chapman House/Teen Savers and Gina's daughter, this would not have been possible. They deserve a lot of credit."
