Peter was photographed gazing lovingly at his beautiful girlfriend while they posed for cameras at the Nordoff Robbins O2 Silver Clef Awards at the London Hilton Park Lane.
Medical student Emily, 23, looked ready for summer in her flirty floral dress and nude wedges despite the drizzle and grey skies in London.
Her swishy long hair was as glossy as ever and she kept her overall make-up look simple.
Emily and Peter began dating last year but although she is frequently seen on his ITV2 reality show, she has made very few red carpet appearances with her pop star boyfriend.
We certainly wouldn't mind seeing more of her on the red carpet, though, particularly when she puts together gorgeous ensembles like this.
Peter, meanwhile, was looking as dapper as ever in his smart suit. He's just returned to the UK from a gruelling charity bike in Zanzibar in aid of Health Improvement Project Zanzibar.
The Silver Clef Awards is a star-studded annual ceremony recognising the best in the music industry. Award recipients this year include Coldplay, Labrinth, The Clash and Barry Gibb.
Peter was on hand as an award presenter, but he has plenty of reason to celebrate in his own music career as it was just announced his track 'Mysterious Girl' has sold more than one million copies since its release.
