Lindsay Lohan's mandatory time in rehab draws to a close tomorrow (July 31), but La Lohan will apparently stick around an additional few days of her own volition, purportedly to make transitioning to the outside world a bit easier.

But when she does leave, she'll certainly jump into the deep end of the pool: She's been confirmed as a guest host on Chelsea Handler's late night talk show 'Chelsea Lately.'

First, LiLo will move to a "lower level, sober living house" for three or four days after rehab to help her readjust to normal life. And while there are plenty of skeptics who doubt anything -- let alone her upteenth stay in rehab -- could straighten her out for good, insiders say she may surprise everyone.

"It's like invasion of the body snatchers. She's a different person," a source told TMZ.

After exiting rehab, Lindsay will reportedly drop all her poisonous friends and do a well-publicized interview and documentary series with Oprah Winfrey. But before all that happens, she'll take over guest-hosting duties for an absent Chelsea Handler on Monday, Aug. 5.

Don't sweat it, Linds. If the Kardashians can do it, anyone can.
