The Mean Girls star has been in and out of jail and rehabilitation centres over the last year (10) after she violated the terms of her probation stemming from a 2007 DUI arrest.
She is currently serving out a three-month court-ordered stay at California's Betty Ford Clinic after failing two drug tests, and will remain in the facility until early 2011.
Her beleaguered career was dealt another huge blow last month (Nov10) when she was dropped from a starring role in a biopic of porn queen Linda Lovelace, but she was reported to have signed up to dance on the hit series in a bid to boost her profile.
However, a spokesperson for the star insists Lohan has no plans to tango her way back into fans' hearts.
The rep tells GossipCop.com, "Lindsay Lohan is not doing Dancing with the Stars. The story is false."
