The actress, who plays Carmel McQueen on the show, revealed the news on Sunday (August 24).
Speaking to the Daily Star Sunday, Gemma explained: "I've had a great time being part of the show for eight years and I'm excited to push myself and explore new avenues."
Gemma added: "I've got an exciting business launch for later in the year that I'm working on. I also have some great storylines before I go."
As the news hit, Gemma took to Twitter.
She said: "Morning all... thanks for all the lovely tweets today. I have loved working at @Hollyoaks for the past 8 years. I have met some great people and have some of the best friends I could ask for.
"I have some great story lines ahead of me and can't wait to get stuck into them. Hope everyone has a wonderful Bank Holiday. xxxx"
Gemma's character Carmel has found herself in the middle of plenty of drama since she joined the Channel 4 soap in 2006.
Remember when her husband Calvin was shot dead on their wedding day back in 2010? MAJOR BLUB.
Carmel's often at the centre of lots of fun and games, too, and Gemma has now been nominated for the Funniest Female gong at the Inside Soap Awards 2014.
Gemma, who also appeared on ITV's Splash! earlier this year, is expected to leave Hollyoaks later on in 2014.
Bryan Kirkwood, Hollyoaks' Executive Producer, said: "I would like to thank her for being a valued company member, and for creating one of our most lovable characters."
As for her future, the gorgeous Gemma plans to focus on her 'exciting business launch' and we cannot wait to find out more about it.
Keep up posted please, Gemma!
