Lindsay Lohan and Dennis Quaid are to reunite online to celebrate the anniversary of the release of classic Disney movie The Parent Trap.
Director Nancy Myers will also join Lohan and Quaid, in the online special, being moderated by veteran US broadcaster Katie Couric.
The get-together is being held to raise money for the World Central Kitchen charity.
Released in 1998, it found Lohan playing the dual roles of Annie James and Hallie Parker, 11-year-old twin sisters, separated at birth who then by chance meet up at summer camp.
They then hatch a plan to get their family back together.
It was a remake the 1961 Disney movie starring Hayley Mills, Maureen O'Hara and Brian Keith.

The movie was Lohan's screen debut and catapulted her to stardom and a host of other Disney movies, including Freaky Friday and Confessions of a Drama Queen, before hitting further acclaim in Mean Girls.
Natasha Richardson, the screen icon who played the twins' mother in the remake, died tragically in 2009 in a skiing accident. She was 45.
Elaine Hendrix, who played Meredith, Lisa Ann Walter (Chessy) and Simon Kunz (Martin) will also appear with Lohan, Quaid and Myers, along with writer Charles Shyer.
