An insider tells Us that the pair split "a few weeks ago" after they started dating this past March. Agron, 28, was seen making out with the aspiring star, who appeared in an episode of Love Child this year, at the Coachella Music Festival in April.
After splitting from Collins, he got to know Agron and the relationship quickly escalated, getting "very serious," a second source tells Us. The pal adds that the blonde star flew to Australia this summer to visit Cocquerel and met his whole family while she was there.
Agron stayed quiet on the relationship, choosing not to confirm the initial coupling, nor commenting on the split. The Zipper star's previous beaus include Dave Franco, Alex Pettyfer, and Sebastian Stan.
