Lindsay's dad, featured on the March cover of Rebel Ink Magazine with Michelle “Bombshell” McGee, has reportedly already begun taping for the VH1 series.

Over the past two months, Lohan has been supporting Lindsay through her grand theft case ... hoping to prove that Lilo is not a thief by providing video evidence of other jewelry stores that have "lent" items to his daughter.

However, just last week, Lohan told a Tampa Bay radio station that ex-wife Dina "did coke" with their 24-year-old daughter. Michael also stated that he wasn't that concerned about Lindsay hanging out with ex-girlfriend Samantha Ronson, as long as the relationship isn't "toxic" again.

As for Season 5 of Celebrity Rehab, other cast members will be Bai Ling, Jeremy Jackson, The Salahis and Dwight Gooden.

This isn't the first time Lohan has tried for a reality show. Find out what his first attempt was ... after the jump.
