Lindsay Lohan asked to be served cream soda when she appeared on talk show 'Alan Carr: Chatty Man' instead of alcohol.

The 'Mean Girls' actress has been striving to stay sober since leaving rehab last July and insisted the comic swapped the customary alcoholic beverages in his drinks trolley for soft drinks, including the fizzy vanilla soda and tropical brand Lilt, so she could join Alan for a tipple during their Q&A which was filmed on Wednesday (23.04.14) and airs on Channel 4 tonight (25.04.14).

A source told BANG Showbiz: ''Lindsay knew that Alan always serves his guests an alcoholic drink when he interviews them, something she couldn't have because she's on the wagon. So she asked for cream soda, Capri Sun and Lilt. The staff had no problem swapping the booze for soft drinks and Alan was happy to accommodate Lindsay's request because he was so happy to have her on his programme.''

Lindsay admitted to Alan that she has had one relapse with alcohol since finishing her latest rehab stint, something her life coach AJ Johnson confronts her about on her reality TV show 'Lindsay Lohan' - which will air in the UK on TLC on Sundays at 9pm from May 4.

The 27-year-old starlet had some wine after getting into an unhealthy romantic relationship and she admits she was frightened she'd ruined all her hard work to get sober.

Speaking to Alan, she revealed: ''There's a moment in the show when I had a drink. I freaked out. I didn't want to say it on the show as I didn't know how it would be taken. I was scared.''

Lindsay has been to rehab six times, but she believes her last spell at the Cliffside Malibu clinic worked because she was ready to change her life and she is grateful a judge ordered her to go after she pleaded no contest to misdemeanour charges stemming from the June 2012 car accident.

She revealed: ''Sometimes I had to go to rehab because of the court situations I had. This time, I just wanted time for me.''
