The troubled actress – whose latest stint in rehab is due to end on Wednesday – is set to take over presenting duties from Chelsea Handler in the August 5 episode of the chat show.
Lindsay is also set to sit down for a tell-all interview with Oprah Winfrey and film an eight-part documentary for the media mogul's channel OWN.
Meanwhile, it has been claimed the 27-year-old actress has made two lists of all her acquaintances with the intention of culling all the 'bad' influences when she leaves rehab.
Out of her 100 pals and family members, 80 of her so-called friends are set to face the chop, TMZ is reporting. There is a possibility her father Michael Lohan - with whom she has a tumultuous relationship - could also be on the list.
The star is keen to stay on the straight and narrow when she leaves her Malibu-based treatment facility, where she is serving a 90-day stint as part of a plea deal for lying to police during a car crash last summer.
