SNL cast stage Lohan intervention

The comedienne behind Lindsay Lohan's most famous movie role staged an intervention when the two met on the set of satirical show Saturday Night Live last week in a bid to convince the actress to give up her wildchild life.

Tina Fey, who wrote Mean Girls and starred alongside Lohan in the dark comedy, joined forces with other SNL regulars to chat to the teenager about her party lifestyle and what it's doing to her health.

A show insider tells American publication Life & Style: "They brought up everything. Nothing was off-limits. Tina told her she was wasting her gift of acting."

Meanwhile, cast member Kenan Thompson reveals: "You just gotta say: 'Sometimes you shouldn't be doing that. You gotta drop that.'"

Lohan's aides insist there was no intervention, but something was amiss at the aftershow party on Saturday night, when the actress appeared to refuse to mingle with the SNL cast.

SNL creator Lorne Michaels reportedly staged a similar intervention the last time she guest hosted the weekly show in May, 2005.
