Palace and Brighton fans may not like each other but each year sets of fans from both teams play each other to raise money for charity.
The game usually takes place as non-league Lewes FC but this year there is a big change; the match will be at Brighton's Amex stadium.
The venue where Glenn Murray scored. The venue where Zaha netted twice in the 2013 Championship. play-off semi-finals.
The Robert Eaton Memorial Fund match has been an annual event since Robert was killed in the 9/11 attacks in New York City.
Since 2001 over £150,000 has been raised for impoverished children in America, Africa, Sussex and Croydon. The REMF fund donated £5,000 to Sutton Eagles in October as a way of thanking the Palace fans that support the charity each year.
REMF vice chairman Brett Mendoza announced the move, saying: "The Robert Eaton Memorial Fund are delighted to announce that The REMF 2016 Challenge Match between fans of Brighton & Hove Albion and Crystal Palace will take place, as a one off, at the iconic American Express Community Stadium on Monday 30th May 2016. 6pm Kick Off
"All seats will be in the West Stand Lower Tier, with food and drink kiosks available.
"A massive thank you needs to go to Paul Barber, CEO of Brighton & Hove Albion, who has given The REMF an amazing opportunity to allow us to stage our flagship event at the most iconic stadium in Sussex.
"Also a thank you to Lewes FC for their hospitality over the last few years, who have given their blessing for the REMF game to move away from Dripping Pan this year. We shall return next season, hopefully with the trophy!
"It would be amazing to see you at The Amex for the REMF 2016 Challenge Match for what is going to an emotional and brilliant occasion. We hope to see you there."
Tickets will be £5 for adults, free for under 16's, and more details on how to get your tickets will be announced shortly.
There will be some as yet un-named former Eagles stars playing too; in previous years the likes of Peter Taylor, Simon Rodger, Robert Quinn, Simon Osborn and Eddie McGoldrick have played.
Members of FYP will be playing too and with Palace narrowly losing last year on penalties this is a great chance to go and see the Eagles hopefully win in Brighton's back yard again.
