The news comes just hours after the professional dancer claimed the BBC show is fixed.
In a lengthy series of messages to her 259,000 Twitter followers, Ola broke the sad news that she's chosen to leave the hugely popular dance series to pursue new things.
She said: "Hi tweeps.... So, yes it's true. I will be leaving Strictly at the end of this series. I have had an amazing 10 years on the show, but things change and I feel it's time for me to move onto other things."

I will be leaving Strictly at the end of this series.
I have had an amazing 10 years on the show, but...
She continued: "I love Strictly and have met some amazing people and made some great friends who I will miss massively. I am so grateful to the show for what it has given me.
"I also want to thank all of you for your continuous support throughout the show. You will never know how much it means to me. I love you all."
Ola, 33, went on the thank her fellow co-stars, saying: "I wanted to finally say how amazing all the pro dancers are. The show is a massive success is because you are all brilliant at what you do.
"Sometimes in life you have to take a step backwards in order to keep moving forwards. Lots of love Ola xxx."
Ola, who was teamed with Iwan Thomas in this year's show, confirmed the news of her departure ahead of Saturday night's Blackpool Tower special (21 November).
Earlier that day, The Sun ran an interview with Ola in which she claimed Strictly is fixed.
Describing how the judges allegedly manipulate the leader board to keep acts in the contest, she said: "Some of the marking is way off. People are over-marked and under-marked.
"In my opinion they know how many votes people scored in the previous weeks and then they try to influence their position on the leader board. Why else would they over-mark someone?

She also called judge Craig Revel Horwood "childish and pathetic".
Ola won the show in 2009 with partner Chris Hollins and is the show's longest serving female star. Her husband James was axed from the show in 2014.
