The reality TV star re-tweeted a loved-up message from his lady on the popular social network this morning, which included a candid photo of them smiling together.
Grace wrote: "Happy Valentines day to my bub ! @oliverproudlock" followed by a number of heart emoticons and Proudlock swiftly replied: "love you bubby!!! X"
The couple began dating last year and are often pictured out and about in London with one another, attending various parties and fashion events.
Last September, Proudlock and model Grace looked like the picture perfect couple, as they headed to Specsavers' Spectacle Wearer of the Year event wearing smart and stylish outfits.
Although the teenage brunette is quite clearly smitten with her man, she has not appeared by his side in any episodes of Made In Chelsea.
But that isn't to say that Grace is shy about her relationship, as she often posts photos on Instagram of herself and Proudlock snuggling up together and pulling funny faces.
