Dianna Agron has given the first glimpse at her gorgeous engagement ring from Winston Marshall. The Mumford and Sons musician reportedly popped the question to Dianna over Christmas, but she has kept her ring under wraps until now.

The blonde beauty flashed her ring while attending the Erdem show at London Fashion Week on Monday. Dianna looked stunning in a blue floral dress as she sat front row at the show alongside Alexa Chung and Daisy Lowe, but all eyes were on her ring, which is believed to be a 4-6 carat diamond set in a simple gold band.

The low-key couple are yet to speak out about their engagement but are said to be "really happy" together. Their romance first came to light in July 2015 when they were spotted strolling hand-in-hand through Paris, where Winston was performing.

They have since made a few appearances together, including the She's Funny That Way premiere after party in August, but have largely kept their romance out of the public eye.

The couple haven't been pictured together in recent weeks as they are both busy with their respective careers; Dianna is filming a new drama Novitiate, while Winston is currently on tour with Mumford and Sons across the US and South America.

Dianna is particularly guarded about her relationships, and previously told The Telegraph: "I don't talk about those things."

The former Glee star has previously been linked to Nicholas Hoult, Alex Pettyfer and actor Thomas Cocquerel, who she dated for nine months in 2014. Meanwhile Winston, 27, was previously linked to Katy Perry.
