Lindsay Lohan's carefully-orchestrated comeback may have gotten a big boost -- some insiders say she's been asked to host the season opener of 'Saturday Night Live.'

“She is definitely considering doing it,” a source told Radar Online. “She loves the show and the people involved.”

LiLo's hosted 'SNL' five times before, but her most recent stint last year was widely panned. Now that she's clean and sober, though, she might be poised for a triumphant return. (Her fresh-out-of-rehab gig guest-hosting 'Chelsea Lately' certainly went over well.)

“Lindsay is doing really, really well. She is going to business meetings and she’s been on time for every single one of them," the insider said. "This is the best I’ve seen her in years.”

But is Radar's source on the up and up? Not according to perennial wet blanket Gossip Cop, which reports it "checked in with a source close to Lohan, who says [Radar's] report is 'not true.'"

But since PR people have been known to fib on occasion (OK, a lot), only time will tell.
