Lindsay Lohan has admitted to drinking again.

The 'Mean Girls' actress - who has been to rehab six times - was confronted by her life coach AJ Johnson on last night's (06.04.14) episode of 'Lindsay' after her mother Dina's claimed they had shared wine, and she then found a bottle in the troubled star's apartment.

However, Lindsay, 27, was furious to be confronted on camera and initially denied relapsing before later admitting to ''screwing up''.

The 'Machete' star - who fled to Los Angeles for a week and failed to contact AJ as planned - said: ''I rushed into a relationship .. and I jumped right into a relationship where we weren't on the same page.

''I wasn't considering the fact that the person I was seeing does drink and yeah. ... I had some wine.

''It's OK to admit it. ... It's really scary. ... It took me a bit to realise, but then I thought, why am I holding this in?

''Yeah, f**k it, I screwed up and that's OK.''

After missing a meeting with Columbia films' Devon Franklin which AJ had set up, the life coach was livid.

She said: ''I was expecting her to call, I didn't hear from her all week. I'm calling Lindsay a friend right now but I feel like there is no consideration.''

And when the actress refused to speak to AJ when she turned up to her apartment the next day, she decided it was time to ''leave before things got ugly'' as she ''cannot help'' Lindsay unless she is ''open to receiving''.

Speaking after her departure, Lindsay said she felt ''disrespected'' over the confrontation.

She said:''I felt like she disrespected me by asking things on camera that were a bit personal. When we had the moments alone to discuss it.''
