Dianna Agron has split from Thomas Cocquerel.

The 'Glee' star - who started dating the 25-year-old actor in March this year - is believed to have called time on her relationship with Thomas "a few weeks ago" according to Us Weekly.

The news follows reports things had been getting "very serious" between the pair - who were first spotted getting close at the Coachella Music Festival in California in April - after the blonde beauty flew to Australia to meet the Sydney-born actor and his family over the summer.

The stars never officially confirmed that they were dating and are yet to comment on news they have split.

Meanwhile, Dianna and Thomas have both enjoyed a string of high profile relationships in the past.

Dianna, 28, previously dated 'Magic Mike' star Alex Pettyfer, 'Now You See Me' actor Dave Franco and 29-year-old Sebastian Stan.

Prior to his relationship with Dianna - who rose to fame after being cast as Quinn Fabray on the Fox series in 2009 - Thomas was in a relationship with Brit actress Lily Collins, 25.

The pair are said to have been introduced through a mutual friend.
