The father of troubled actress Lindsay Lohan – who was ordered to spend 90 days in rehab last year after failing a court-ordered drug test – flew to the Inspirations for Youth and Families clinic to work alongside people living at the facility and also film a commercial to promote it.

He told website “I'm going to be doing interventions. Lindsay is 100 per cent behind what I'm doing and I look forward to this entire journey not only with my family but with the Inspiration youth programme as well."

Michael attempted to stage an “intervention” on Lindsay last April, flying to Los Angeles in a bid to get her to enter rehab, after he believed she was addicted to prescription drugs – prompting an angry reaction from Lindsay who referred to him as her “ex dad” and accused him of ruining his own brain with drugs.

However, the pair later reconciled their differences and Michael – who is also father to Ali, 17, Cody, 14, and 23-year-old Michael Jr. with ex-wife Dina – recently spoke of how proud he is of Lindsay for finally facing up to her substance abuse problem.

He said: "We went to an AA meeting last night then went home and had a quiet night.

"She changed back to the girl she used to be. When she was at her best - literally. She's done a 180 and I'm very proud of her."
