The singer/actress reportedly began dating the British hunk in May (13), but Gandy, who previously romanced The Saturdays pop star Mollie King, has now confirmed he is single again.
He tells Britain's Mail on Sunday, "I am single at the moment. This summer I am going to L.A. and then New York. Samantha's gone to L.A. now and if I see her in L.A. then I see her in L.A. I am not going to go out of my way to see her, but if I bump into her, I bump into her."
The split is the second this year (13) for Barks, who parted from Welsh Tv presenter Matt Johnson before she started dating Gandy.
