The 47-year-old claimed that she has been working with the troubled Mean Girls star as she strives to conquer her addictions.
"I've taken up Lohan because nobody else will," Love told Details.
However, a rep for Lohan denied Love's claims, saying that the singer has made no attempts to contact Lohan.
"Courtney Love is not, nor has she ever been, a sobriety coach to Lindsay," the spokesperson said.
In November, Lohan completed her jail sentence for probation violation, spending four and a half hours at the Century Regional Detention Facility.
The sentence was delayed due to the actress's Playboy shoot. Lohan will appear on the cover of the magazine's January/February issue.
