It was announced earlier today that show bosses are bringing back the character with a new actor in the part.
Anderson, who previously played Sonny between 2006 and 2007, took to Twitter to support the news.
He said: "Wanna say a big congratulations to @AaronFonts for signing up to Hollyoaks as the new sonny valentine....I have no doubt he's gonna smash it."
He will without a doubt be a very different and a lot better incarnation of the character otherwise he would not have been cast!! Enjoy— Devon Anderson (@DevonAnderson87) November 28, 2013
Fontaine responded to the tweets by saying, "Hats off to you Sir Thank you Brother. Its appreciated. Love always my friend!"
The two actors already knew each other before Fontaine was cast in the role.
Anderson is also known for his role as Billie Jackson in EastEnders. His original stint in the show ran from 1993 to 1997. He reprised the role in 2010, but the character was killed off later that year.
