Love Island's Abi Moores has taken her relationship with Married at First Sight UK's Nathan Campbell up a notch, as she flaunted a massive diamond ring on Instagram. The reality TV star recently celebrated her 27th birthday and shared glimpses of her special day on her Instagram Stories. The pair, who reportedly hit it off after meeting earlier this year, made their first public appearance together at a party for BBC Radio 1's Big Weekend last month. They later posted snaps from the event on their individual Instagram accounts. Abi gave fans a peek into her birthday celebrations on her Stories, showing off one of Nathan's gifts to her - a bottle of white wine, a collage card featuring pictures of them together, and some jewellery from H Samuels. "Nath pulled it out the bag," she captioned the post. Later in the evening, she posted a video showcasing the stunning diamond ring he gifted her, although she wore it on her right hand. She also posed for another snap in front of red balloons and a '27' balloon. Nathan went all out for Abi, decorating a room with countless red balloons, including ones that popped the question - 'Will you be my girlfriend?', reports the Mirror. "Nathan did not hold back when it came to putting on a lavish display for Abi," a source told The Sun, commenting on the romantic gesture. "Abi couldn't be happier and immediately said yes - she feels like she's finally found a keeper in Nathan," the source added. Abi recently opened up about how their mutual pal Reuben Collins played cupid by setting them up at Sellebrity Soccer. "I turn up and Reuben said he was going in the changing rooms and he'd be right back and then he sent Nathan out, and he said 'Reuben, told me to come and speak to you because you fancy me," Abi recounted. When they went public with their romance last month, the couple was flooded with congratulatory messages. Hannah Elizabeth dropped several heart emojis, while Demi Sims commented: "Awweeeee so cutes." One admirer confessed: "I saw you both today and was too starstruck to say hello! You both make such a cute couple," while another exclaimed: "Wow Nathan im so happy for you."
