The singer admitted her affection for the model's breasts and couldn't hide her feelings any longer after the two spent the evening together at the ELLE Style Awards on February 24.

Taking to Twitter to praise her pal, Ellie wrote:

Meanwhile, Cara picked up the Best Breakthrough Actress prize at the ceremony before clearly being pleased with Ellie's comment and retweeting it to her 2.25 million followers.

Cara wore a plunging black gown to the event, but seemed to have a few issues keeping her assets in check whilst posing on the carpet, with them threatening to make a break out at times.

Ellie's confessed love of Cara's chest is not the first time she has publicly shown affection for her friend as the pair shared a smooch on the lips at London's Hyde Park last July.

The 'Anything Could Happen' hitmaker took a break from watching her boyfriend Dougie Poynter's band McBusted perform to plant a kiss on the beauty, which came shortly after Cara split from her on/off lover Michelle Rodriguez.

A source said at the time: "Ellie and Cara got up on some mates' shoulders. They went in for a hug but it quickly turned into a passionate kiss."
