The JLS singer tried to woo the American rapper by sending her witty tweets, but when they met up in person this summer she wasn`t too impressed with Ortise`s offer of a date.
He sighed: "We had a thing going on twitter for a while. She came over for the V Festival and we got chatting and I said I`d love to take her out and we left it there.
"She hasn`t got back to me. So I`m still looking for love. Any nice girls out there? Hit me up!"
Not only is the `Makes Me Wanna` singer having no luck with the ladies, he is also getting no sleep on the JLS tourbus thanks to his bandmate Marvin Humes` love of practical jokes.
Ortise added to We Love Pop magazine: "Marvin is more of a prankster than people realise. He`ll set my phone alarm for 3am, then place it next to my head on the tourbus. When it goes off, everybody moans at me, and I`m like `I didn`t set it! I didn`t set it!`"
Newlywed Marvin could be acting up because he misses his wife Rochelle, who he didn`t see for five weeks after their wedding because she jetted off to Los Angeles to film her new reality show with The Saturdays.
He confessed his days as a party-mad singleton are firmly behind him, saying: "I`m always doing DIY! I even wallpapered a room in my house. I`m also a master at cooking breakfast - Rochelle will tell you that.
"Things definitely feel different in our relationship - we feel a lot closer."
