Zedd is hoping to "seal the deal" with Selena Gomez.
The music producer is reportedly hoping to woo his rumoured girlfriend by doing something romantic for her on Valentine's Day today (14.02.15).
A source said: "[He] can seal the deal with her if he really brings it with the romance, she really wants to be loved and Zedd has a real good chance to be the man, the ball's in his court."
The 'Come And Get It' hitmaker is set to release a track with the 25-year-old DJ called 'I Want You To Know', which has meant the pair have been spending a lot of time together, something that is working in Zedd's favour as he competes for Selena's attention against her on/off boyfriend Justin Bieber.
The source added: "The thing that is helping Zedd right now is that he is spending tons of time with her thanks to the song.
"He has been showing her that he is the right guy because he is really nice, fun and creative."
Meanwhile, it is believed to be "likely" that the 22-year-old singer will be moving on from the 'Boyfriend' hitmaker for good.
Another source told HollywoodLife.com: "She will always love Justin and there is still something there but the relationship with Zedd has really made her let go and the chance of her totally moving on from him is likely."
