VICK Hope flaunted her massive engagement ring 

 at Radio 1's Big Weekend yesterday

just days after her engagement to Calvin Harris was announced.

Last week, the 32-year-old TV and radio personality

and top DJ Calvin, 38, made their  

relationship public at the Chelsea Flower Show.

When Calvin proposed on his Ibiza farm

their whirlwind love had already been taken to the next level

Vick and co-host Jordan North talked to the Big

Weekend crowd in Coventry yesterday, looking energised.

Her enormous rock drew the eye as  

she waved around notes in her hand, 

and she shone in a dazzling bralet and denim hotpants.
