The 29-year-old, who rose to fame with the professional dancer when they fell in love on Love Island last year, took to her official Twitter account to break her silence.
Taking to her account, the Irish beauty tweeted out to her 169,000 followers quite the cryptic message following news that Curtis had been spotted kissing Amber Pierson.
Maura tweeted: "The truth always comes out in the end."
Her tweet comes shortly after Curtis was spotted sharing a kiss with blonde beauty Amber, as the two went on a stroll during a romantic date.
It was rumoured that the reason behind Maura and Curtis' split was because she had accused him of cheating with the 21-year-old.
In the photos, Amber can be seen wearing a pink hat, skater skirt and a crop top, she looked effortlessly stylish as Curtis wrapped his arm around her shoulder.
The pro dancer, who finished in fourth place on Love Island last year, wore a pair of casual shorts and a beige T-shirt as he chatted with Amber.
Earlier this year, Curtis had been accused of cheating on his girlfriend Maura Higgins with the dancer, a claim both Curtis and Amber have strongly denied.
When contacted for comment by Daily Star Online, a spokesperson was unavailable for Curtis.
Maura, 29, and Curtis split back in March, with the Irish bombshell breaking the news in a heartfelt statement over Instagram.
Admitting there were "no bad feelings" between the former flames, she said: "Curtis and I have made the decision to separate.
"We enjoyed a great experience from our time in the villa and want to thank everyone for supporting our relationship.
"There is no easy way to get through a breakup and no bad feeling on either side. We tried to make it work, but it wasn’t meant to be and I wish Curtis nothing but the best for the future."
