Former X Factor judge Tulisa dated the multi-millionaire playboy during the summer however their relationship has fizzled out.
Tulisa, who made a brief return to The X Factor at Judges' Houses last weekend, is now focusing on her music career rather than finding love.
Speaking to The Mirror, Tulisa said: "I've been single for a month.
"I was seeing someone but we're not together now. I'm not looking for love." Tulisa, 26, then added that she is "married" to her music.
After a rough year, Tulisa has picked herself up and is now back in the spotlight. Along with helping Louis Walsh at Judges' Houses in Bermuda, Tulisa made her return to the red carpet earlier this week at the Pride Of Britain Awards.
The N-Dubz star stunned at the event, held at the Grosvenor House hotel, by showing off her slender figure in a textured black floor-length gown.
Following the ceremony, Tulisa tweeted: "Such a lovely evening at the Pride of Britain Awards."
The star has spent the past few months holed up in the recording studio and is hoping to unleash her new music on fans very soon. Tulisa has said she is "proud" of her work, adding that the emotion of the past year has been added into her songs.
In June, Tulisa appeared in court accused of setting up a drugs deal but she walked free after the trial collapsed and the judge threw the case out.
