Lindsay Lohan had a novel way of staying off the booze last night. The 22-year-old actress had a flunky by her side to sip each of her drinks to make sure there was no alcohol in them.

We can think of a simpler way —order your own drinks instead of relying on the free ones.

Alcohol free: Lindsay Lohan, pictured with Sam Ronson, even ignored the booze in the back of the car last night

LiLo, who went into rehab last year after admitting she was addicted to drugs and alcohol, was at Dolce nightclub in Soho where her girlfriend Samantha Ronson was DJing.

Our spy said: “Lindsay was determined to stay off the drink, and had a man to sip from her glass every time she got one to make sure there was no alcohol in it. Even when 12 waitresses arrived with champagne bottles with lit sparklers attached, she still wasn't tempted to drink.”

And it wasn't just the booze that LiLo was saying no to. X Factor choreographer Brian Friedman suffered an embarrassing snub when he tried to cosy up to the girls at their VIP table. Our spy added: “When he approached their table to try and talk to them, he was moved away by security.”

Arts clubber: Lily Allen

And as she was leaving, LiLo threw a diva fit at her minder as their limo wasn't waiting close enough to the venue. They then headed to the Notting Hill Arts Club, where Lily Allen was watching a real DJ — her ex Seb Chew.
