The Donnie Darko hunk first asked Kelly out last autumn (11) but she turned him down and began dating Wilmer Valderrama instead.
But when that relationship died in April (12), Kelly agreed to take a chance on Gyllenhaal.
A mutual friend tells Us Weekly magazine, “Minka wasn’t into Jake when he first pursued her. (But she) decided to give Jake another chance.”
However, the match wasn’t meant to be and the would-be couple quietly parted ways. The insider adds, “It was never serious, and it’s over now.”
Serial dater Gyllenhaal has been linked to singers Taylor Swift and Jenny Lewis, as well as screen beauties Olivia Wilde, Kirsten Dunst, Reese Witherspoon and Rachel Bilson.
