YouTube’s Joe Sugg, 31, and girlfriend Dianne Buswell, 33, put on a united front on the red carpet of the launch night of the BBC Earth Experience on March 29, despite continued rumours of their split.The couple looked the picture of happiness as they smiled for the camera and matched in blazer jackets whilst they had their arm around one another on the green carpet in London. Joe wore a beige turtleneck jumper under a beige buttoned-up blazer, while red-haired Dianne wore a checkered blazer and a stunning silver necklace, as they matched in black trousers.The loved-up couple met during Joe's stint on Strictly Come Dancing back in 2018 and bonded as dance partners before they fell in love and became official soon after it ended. The duo seem to have gone from strength to strength since, and live together too, though they have recently put their swanky Sussex home up for sale.
